Customer Reviews (4.8 / 5 · 5 reviews)

Steven I. ★★★★★

These shoulders are dead-on precise, the ground finish lets them spin freely in a bearing without any wobble. Packed 25 to a box, they're a solid staple for any jig or pivot I'm building.

George ★★★★★

The precision-ground shoulder on these screws made them perfect for a jig I built, fitting smoothly into the bearing surface without any wobble. I’m glad I went with stainless steel for the corrosion resistance, and the hex drive seated cleanly with my Allen wrench.

Leo Q. ★★★★★

Installing these as pivot pins for a small clamp mechanism I'm building, the hex drive made seating them flush incredibly easy. The stainless finish is clean and smooth right out of the package.
