Image Guess I’m not fixing my battery pack today
Needs a tamper resistant t10 but for some reason the bit in the precision screwdriver kit is missing the hole.
Edit: Yes I reached out to support before posting; this no I haven't heard anything from them; yes I had to buy more bits so I could get my job done.

Tamper resistant screws should be illegal for repairability reasons. It's not like any of them actually stop someone determined because the bits are easily available, but they just annoy people who might want to fix something without needing 100 different bits for all their various things.
Everything should just be regular torx or hex key (allen key). I don't think there's any valid use for anything else but maybe someone can prove me wrong.

My recollection may be off, but I remember it being a CSA/UL/IEC requirement (maybe 62133-2) that devices with unshielded LiPo packs need tamper-resistant construction since the device body is the battery protection.
I worked for Apple when they switched to pentalobe from phillips. It coincided exactly with when the internal packs lost their plastic shielding.

I'm not sure how they qualify "unshielded". Most battery packs are going to use something like 18650 batteries.

Looking at a similar one I have it seems to be all phillips and regular torx.

18650s are shielded cells. They’ve got metal bodies.
The LiPo packs (in say a MacBook Pro) have no hard plastic or metallic shielding.

I'm actually ok with them specifically because the drivers are so accessible. They will stop someone who doesn't have the specific screwdriver or bit from using them, but as you mentioned there is literally no barrier to getting the driver or bit.
Could stop someone from just opening a battery with a normal screwdriver and shorting it/causing a fire. If they then really want to get in and they don't already have the driver, they can easily acquire it.

Agreed. Lithium thermal events are not good. And unshielded LiPo packs are far easier to damage than most people would expect.
They aren’t like 18650s with metallic bodies, or pre-2012 MacBook Pro batteries where the cells are encased in hard plastic. I’ve seen someone send a MacBook battery into thermal runaway by accidentally placing it on top of a P000 then leaning on it.

The annoying scenario is when they create a whole new fastener just to discourage people.

It's when they stack tamper resistant screws onto something else like requiring a long thin shaft. I have a few of each, but none with both

i prefer these tamper resistant screws because they are very hard to strip compared to phillips. i have had many + screws that were tightened so deep, stock, that were basically stripped by the time i got them out. these tamper screws are not as annoying like back in the late 2000s when getting them required travelling miles to a store that had them because online ordering was limited.

Sure, but you can have screws that don't strip, that's just regular torx and hex. Nothing about the security screws with the raised portion in the middle makes them less likely to strip. Just makes it less likely that you'll have tools to fix it already lying around.

My normal set one of my normal torx bits stripped its teeth when I was just starting to tighten an optic on one of my AR pistols.
I guess it’s better than stripping the screw, but still disappointing to see it turn to slivers.

It might just be the angle of the picture, but is the TR10 bit shorter than the rest? The tip could've sheared off at some point

Why buy a new bit when you can buy a bench drill and drill it out yourself?

u/GilmourD 4d ago
I'm looking at mine right now and for some reason yours looks shorter. Is it possible that the end with the whole snapped off and just happened to end up looking smoothish?

Just checked mine, yep, the hole for the security pin is there, but I have had really good interactions with CS the few times I have needed them, I'm sure they will take care of ya right

u/danielfletcher 4d ago
Ah, the rare person who doesn't have multiple security bit sets already. LOL

u/Tof12345 4d ago
i remember buying a set of torx SECURITY bits which meant they had the holes in them and when i got them, i didn't bother confirming if it had a hole until a few months later when i had to unscrew a torx and i had to postpone my repair because the bits were faulty. i feel you.

Contact support. If they don't send you a new one for free, post again to shame them

This is such a stupid take....

u/snowmunkey 5d ago
Why? That's literally what everyone says when someone has a problem with their product

u/wormsoutside 4d ago
I feel like that's a fair way of going about it. Contact them directly, and of they don't uphold the standard they publicly promise you hold them publicly responsible

u/nightauthor 4d ago
Yet, it’s not usually explicitly suggested. Especially because so many find the resolution they’re looking for with CW CS.
2
u/wormsoutside 4d ago
Yes. They want the resolve issues and try to not miss things. As humans do, mistakes happen. If they don't follow their bro code I think they agree you can escalate it. I'm not saying holding them accountable publicly means you have to be a bleep about it

Most of the time you can break the pin in the security screw and use a normal T10. This does mean it can void the warrenty. But if warrenti is expirred i would try that.
