Joshua ★★★★★

The precision-ground shoulder on these screws made them perfect for a jig I was building where the alignment needed to be dead-on. They fit the bearing surfaces smoothly without any binding. I'm glad I went with the stainless for the corrosion resistance.

Sofia ★★★★★

The precision-ground shoulder made these screws perfect for the small axle I needed in a folding mechanism—much better than using a standard bolt. The hex drive seated cleanly without any cam-out.

Christopher D. ★★★★★

Used one as a pivot for a custom jig, and the fit was spot-on — no wobble at all. The stainless steel finish is nice and clean, too.
