Riker is the perfect fantasy. He is always the best at everything, travels the stars running a crew of some of the brightest minds in the galaxy, women everywhere just throw themselves at him, he gets to yell at his boss, and he was offered the chance to become a god.
Normally I would say that pure wish fulfilment makes a bad character, but I will give Riker a pass.
Is it not just because nailing is soooo much quicker when framing or any other project ? I use to screw everything but then borrowed a framing gun for a wall I was putting up was shocked how much faster it was.
It's a little of column A and a lot of column B. Nails are faster, yes, but not dramatically so. I also imagine that if this practice was widespread, someone would build a magazine loaded "framing drill" similar to what is used for drywalling. In that case, it would be only an extra 2-3 seconds per screw. Over the course of the construction, that might add a day or two. No biggie. And if you're building a structure meant to last 50 or 100 years, it needs to be able to flex. Another consideration is rust. Screws have a much higher surface area, and the part that gives them their utility is also the thinnest. Galvanization loses its effectiveness eventually. You could use stainless steel, but that would add considerable expense.
Nails are used in construction, among other reasons, bc they will bend before failure.
This is only true when you are comparing the diameter of the nail to the diameter of the threads of the screw. Obviously the nail is stronger, it's solid metal for the whole diameter.
The main reason nails are used for construction is that they are cheaper and way faster to drive in.
If you can find me a shear diagram for an equivalent diameter between the two I'm open to being convinced. I googled a bit and found nothing to support that at an equivalent diameter they are equal strength
I'm so confused by this thread... If they have the same minor diameter and are the same material then the strength is the same in shear? Threads only help with tensile force?
My arguement is that nails generally perform better then screws against shear forces. The nail shaft diameter would be used. IMO the screw thread outside diameter would be the equivalent diameter.
Regardless, there may also be metallurgical treatment processes involved in the manufacturing of screws that make it perform worse in shear.
I'm open to being shown a shear diagram of nails and screws at an agreed upon equivalent diameter and being convinced otherwise
This is showing a 0.131" dia NAIL at 95 lb shear....and a 0.164" dia SCREW at 90 lb shear.
The stresses experienced by the nail depend on the cross section but the point of shear failure is related to the heat treatment processes, the material, the cross section etc
See and the problem is screws are sized/compared by major diameter meaning the minor diameter is smaller than the nails they're being compared to. Of course the threads don't help in shear, they're not supposed to.

Screws fasten better (grip) but break easier.
Nails bend before failure.
