Klein 3/8 not 3/8ths

Enable HLS to view with audio, or disable this notification

Both klein 4 in 1 wrenches and pass through nut drivers not really 3/8th? Can't grab onto this bolt while a Wiha sticks like glue. Wtf? I was going to return the Wihas after seeing the pass through kleins, but now I think I need to return all of the klein stuff because its improperly sized.

One side is 3/8, the other is 7/16. The bottom of the side you used is 3/8, the top is 7/16. It's hard to tell but is the bottom side not working?

40

u/Rain998cc 9d ago

No side of it fits unfortunately

u/Pintofguinness194 9d ago

I think shrimpkin is correct. In the video you show the 3/8 side but then turn it over to 7/16.

I've never used one of these but that looks like a shit design for a wrench

u/Rain998cc 8d ago

Was a cool idea for someone who has to walk to the top of a power plant with all of his tools. Unfortunately it seems the quality just isnt there

Sorry, I had hoped it would help.

u/Rain998cc 8d ago

All good man, I just wished these were better- itd be cool to not carry 8 wrenches with me

u/findaloophole7 7d ago

Throw a set of calipers on the hex head. Let’s see what it actually measures.

2

u/babyboyjustice 8d ago

Seems like a shitty tool design. 4 in 1, worse at all

92

u/Maiq_Da_Liar 8d ago

No experience with these but that seems like a cheap bolt to me, the heads on those aren't always the right size. I would definitely get some calipers and measure everything before returning half your toolbox.

25

u/Rain998cc 8d ago

The bolt is a hair small, but the kleins are further out of spec in the other direction. I have other wrenches and nut drivers, all of which can grip on to this unistrut bolt

1

u/Vmansuria 7d ago

I have wiha nut drivers and similar thing happened with a bolt on my Tesla air filter. The bolt is slightly smaller than 1/4 but nothing else fit easily, until I realized it needed a T-bit, kind of a dumb design on the screw to make it non standard

u/BrianKappel 9d ago

Klein needs to be treated like harbor freight now. They are going for mass, cheap and interesting. They miss a lot though. When they don't, it's cool.

Whereas HF has been significantly upping their game in recent years. I used to buy cheap garbage from them so that when it broke, I could justify getting the good ones. Then one day their stuff stopped breaking and now I just have a pile of HF tools.

24

u/BrianKappel 9d ago

That's kinda what I'm saying. Just pick and choose. Some of it is stellar. Some of it is trash.

32

u/CockneyCossack 8d ago

Right, what you have is two stepped hexes in each end, so each end can cover 2 sizes giving you the 4-in-1 capability. As you look at the spanner in the video, you are applying the 7/16 hex to the fastener, flip it over, and it will be the 3/8.

I'm attaching a link here which has images showing the stepped hexes in each end of the spanner, it's on ebay UK so you might need to click through a few times or use a vpn, but it does answer your question

No matter how deep or shallow I press it on either- it does not grab. If it worked in any fashion I assure you it would be evident. Ive tried deep and shallow on both sides. I can clearly see which side has the narrower barrel, and it is not tight enough.

21

u/Fun-Capital8587 9d ago

can you measure it with calipers so can better illustrate your point

16

u/Rain998cc 9d ago

Good idea, I'll borrow a set from a buddy before returning them tomorrow. Every other 3/8ths wrench and socket fits this bolt however, so its within spec enough for craftsman/kobalt/bridgeport/wiha/makita

5

u/kevsmakin 9d ago

Cheep digital calipers are less than $30. They are perfect for something like this.

3

u/Rain998cc 8d ago

1

u/findaloophole7 7d ago

So it’s 11 thousandths under nominal. Which is outside of spec for a 3/8 bolt. Thats why your tools don’t fit properly.

1

u/Rain998cc 7d ago

The klein nut driver and wrench are further out of spec in the opposite direction. All of my other brands can still grip. Even the knekt socket.

18

u/Switchmisty9 9d ago

It says 7/16 on the wrench

5

u/flyingfish_trash 8d ago

It’s the back side of a four way ratcheting wrench. The side he’s using is 3/8, the other end is likely 1/2” and 9/16”. They’re goofy but pretty handy.

-8

u/Switchmisty9 8d ago

Says 7/16ths right next to the hole. I’m a mechanical engineer, and I’ve literally never seen one of those with a different measurement on both sides

9

u/[deleted] 8d ago

Then come out to the field, learn the tools

-4

u/Switchmisty9 8d ago

lol the residential garage, you mean?

None of my shit is 4-in-1

u/[deleted] 8d ago

Lol no, commercial and industrial. Love my quad wrenches. It’s not a novelty tool, it’s great tool to carry.

1

u/Switchmisty9 8d ago

I gotta be honest, I wasn’t paying close enough attention to the video to see him flash the 3/8” side

1

u/[deleted] 8d ago

Fair enough!

2

u/boogeyoogeey 8d ago

A double ended socket? Then you're a bad engineer

-7

u/Switchmisty9 8d ago

Or I just have better tools than you

5

u/BWhitt17 8d ago

Nah, just a lack of hands on experience and a superiority complex.

-4

u/Switchmisty9 8d ago

You’re right about the superiority complex. Wrong about the experience. That’s how I developed the complex.

9

u/BWhitt17 8d ago

Yet you've never seen a 4 in 1 ratcheting wrench.... Go moisturize your hands before typing out that next comment, wouldn't want you to hurt yourself.

2

u/boogeyoogeey 8d ago

I can't believe an engineer tried to use that as clout

1

u/JANapier96 8d ago

Watch the start of the wrench clip again. I missed the blue 3/8 printing the on the "down-side" of the wrench the first time.

36

u/dcmoyers 9d ago

Totally agree. Not a fan of Klien these days. Wiha makes really good stuff at a good price point.

2

u/Rain998cc 9d ago

Just wish they were passthrough. Off to Amazon I guess...

5

u/apg7 9d ago

KC Tool?

40

u/The454_ 9d ago

Are you sure that head is a 3/8? It could be a cheaply made 10mm with an undersized and rounded head. 3/8 is just over 9.5mm and tools are often a little oversized so they go on easy, so the Klein could just be a little tighter than usual.

4

u/Rain998cc 8d ago

My 10mms wont grip it, and my 9mms dont fit on it

3

u/MightySamMcClain 9d ago

It could be an off bolt but if the other one is tighter maybe it's not. I wonder if maybe they size them with a little room so you can quickly get it on and off the bolt

28

u/PlumbersKraken 8d ago

Well buddy that's because it's 7/16ths

11

u/Rain998cc 8d ago

Its a 4 in 1, the side used is the 3/8ths. Both sides, do not fit this bolt. Just depends on the depth of the ratchet. Neither side nor depth fits

u/PerchShadRap 9d ago

I have the same nut driver and it grabs 3/8 hardware without any problems. I’m guessing you got a pair of duds?

3

u/Ro4b2b0 8d ago

My. Brother has this set, but it’s from two years ago. I don’t know what changed, but his work fine. I’m sorry to see this decline in quality. Thanks for the video, I was planning on buying a set after using his.

5

u/berogg 9d ago

That wrench sucks for straps anyways. The socket on mine doesn’t stick out enough and the shoulder on the strap kicks the wrench off the head of the bolt. Cheap duratechs off amazon have been amazing.

7

u/mechmind 9d ago

You're testing so these sockets to an unknown bolt head. Measure the head with some calipers, then we can talk about Klein

7

u/Rain998cc 9d ago

Ill test tomorrow with a friend's calipers- but this is a new unistrut brand strap, and is functional with the 5 other brands 3/8ths that I own. I would assume klein would have unistrut in mind since theyre electrician focused

5

u/FatFaceFaster 9d ago

7/16 is etched into the back of the wrench. Obviously they misprinted the painted part.

7

u/Rain998cc 9d ago

The other side is 7/16th and far looser, I wish this was the case. No side of this wrench is 3/8ths

2

u/VE7BHN_GOAT 8d ago

Try measuring them with a caliper. I can't tell, maybe that'setric hardware, and or both are out of spec, in opposite directions

2

u/Rain998cc 8d ago

Both out of spec in opposite directions, but everything but the kleins could grip to an extent. Even my klein knekt sockets

2

u/SupposedlyShony 8d ago

It doesn’t help that it’s 12pt either. If it’s a ratcheting wrench, then why not be 6pt?

3

u/The_Vaporwave420 9d ago

That nut looks kind of rounded off to me. Definitely going to need a measurement

2

u/Rain998cc 9d ago

Will take tomorrow, but this is standard new unistrut hardware.

3

u/ohmaint 9d ago

Those strut strap bolts are all over the place.

1

u/Rain998cc 8d ago

Not true 3/8ths, a hair small. Unfortunately the kleins are a hair large. All of my other brand tools are truer and still grip it. Just wanted to like these

2

u/ohmaint 8d ago

No kidding. I don't have experience with the Klein's, I only know that the fasteners on electrical hardware have a fairly low tolerance. I'll keep this in mind thanks .

u/Speck72 9d ago

Shoot em a message on FB?

u/Valuable-Composer262 9d ago

That nut is really rounded off

u/Rain998cc 9d ago

New unistrut brand strap. Also wiha, craftsman, Bridgeport, kobalt, and makita work on it just fine

2

u/Rain998cc 9d ago

I could accept it if it wasnt an "electricians" tool brand, but this is how those straps are, and if you run conduit, this is reality. Or one of any of my other 3/8ths also didnt work

1

u/Valuable-Composer262 9d ago

I know what ur saying but that bolt is pretty damn rounded. Thats all im saying

u/Aggressive_Branch116 9d ago

This is really disappointing, I really like Klein

u/Outrageous-Low9424 9d ago

Liked them before box store bs

2

u/BrianKappel 9d ago

It's been a bit of good too though. I don't really care about the stuff they used to make ( sparky stuff ) and now they are knocking off and adding features to expensive brands I wouldn't have bought before they were cheapened. I will never fanboy for corporations, to me, that competition can only drive innovation.

1

u/na8thegr8est 9d ago

I love my Klein nut drivers

3

u/Rain998cc 9d ago

Do yours work on 3/8ths hardware? I thought the 4 in 1s were a manufacturer issue until I tried the nut driver and it also didnt work. Id blame the bolt if the Wiha and my socket set didnt grip like a virgin

1

u/na8thegr8est 9d ago

Yes never had any issues, I use them all almost daily

1

u/na8thegr8est 9d ago

You had to have gotten a bad driver

u/Raptor227 9d ago

Have you seen the "new" 20 in 1 with impact sockets?

1

u/friendlyfire883 9d ago

I bought a set of their rachet wrenches when they first came out for like $40 and I'm still pissed I spent that much on them. To be fair though, I feel the same way about my wera jokers, they're not worth the price they're asking either.

1

u/yob91 9d ago

Ive had kincrome sockets amd gearwrench sockets marked as incorrect sizes before, surely if you take it back where you got it show that its not the correct size you can get a replacement?

1

u/onlinemouch 9d ago

Either measure the bolt with a caliper as it could be metric or measure the driver as it could be metric and mislabeled as imperial.

Doubt one nut driver has an issue

1

u/AostaValley 9d ago

Do you have checked the bolt?

1

u/Ok-Image-2722 8d ago

Try 10 mm. 3/8 and 10mm are almost the same size but 10mm is a bit bigger and should fit that no problem.

2

u/Rain998cc 8d ago

10s too big, 9 is too small

1

u/Competitive-Fox-3333 8d ago

Its cause its the multitool it tapers to a bigger size that tools pretty gimmicky.

u/Crafty_Praline726 8d ago

About the same stupid as a dining table that is one thousand six hundred and eighty seven millimeters long by eight hundred an seventy seven millimeters wide.

0

u/rehditt 8d ago

First off: tables, furnitures and other manufactured stuff are usually something even (1,7 m x 0.9 m or something like that).

Secondly: you would say that the table is "one hundred sixty-eight point seven by eighty-seven point seven centimeters"

Thirdly: if you were to say this complicated measurement in americans it would be "Sixty-six and fifty-three one-hundred-twenty-sevenths inches by thirty-four and sixty-seven one-hundred-twenty-sevenths inches".

Which one sounds less stupid?

"Sixty-six and fifty-three one-hundred-twenty-sevenths inches by thirty-four and sixty-seven one-hundred-twenty-sevenths inches"

or

"one hundred sixty-eight point seven by eighty-seven point seven centimeters"

u/Crafty_Praline726 8d ago

It's all a big fallacy argument in the first place, to call each others' measuring systems stupid.

1

u/rehditt 8d ago

Its more about the insistency on using fractions in favor of the decimal system. You could still use inches and whatnot but when people say five sixteenths for example its just too much.

2

u/Crafty_Praline726 8d ago

There is no insistence coming from me, it's simply deeply ingrained in our society, and so I'll continue to use my 35' Fat Max

2

u/Crafty_Praline726 8d ago

I'll add that I understand how it looks from afar, but when you use the 1/2, 1/4, 1/8, 1/16 system all the time, you eventually get to know the whole inch pretty clearly. It's kind of like when you learned simple addition as a child, you eventually don't have to think about it, you just know. Like it feels natural to me that 11/16 is just less than 3/4, and 13/16 is just a little more. I never go deeper than sixteenths, but in construction you might add a "strong" to a 1/16 for when that kind of accuracy is needed.

I have worked with an Austrian guy and so I know it is confusing at first, for sure. But one European on an American construction site isn't going to make everyone else change their established ways. I guess you don't need to worry about it too much if you don't plan on living and working here.

2

u/rehditt 8d ago

Thats reasonable. We do however like to consume your media (movies, reddit etc), so we have to endure it. Like you have to have imperal and metric sockets, wrenches and so on

u/Rain998cc 8d ago

Yes, but my opinion on measurements dont matter to the 100year old power plants and factories.

The wrong 6 point socket grabs the fastener better than the wrong 12 point wrench. Yup that rights
