I needed some sturdy pivot pins for a custom jig, and these shoulder screws turned out to be exactly what I was looking for—the hex socket drive made installation a breeze.

The precision-ground shoulder on these screws made them slide perfectly into my bearing housings without any filing or adjustment needed. They're holding up great as axle pins on a custom jig I assembled last week.

I used them as pivot points in a jig I built, and the hex socket drive made installation much easier than a standard hex head. The threads cut cleanly into my steel plate without any binding.
