Julian ★★★★★

I needed a precise pivot for a jig I’m building, and the ground shoulder on these screws is so smooth it spins without any wobble. The stainless finish looks solid, and the hex socket drove in perfectly with a standard Allen key.

Joshua ★★★★★

These are great for replacing cheap pins on some woodshop jigs I use; the 3 1/2" length is perfect, and the stainless steel finish feels smooth.

William W. ★★★★★

The precision-ground shoulder on these screws was exactly what I needed for a smooth axle on my project. They fit perfectly and the stainless steel finish looks clean.
