Abigail ★★★★★

I used these as pivot pins for a folding mechanism and the precision-ground shoulder made for a smooth, tight fit with zero wobble. The stainless steel finish feels solid and corrosion-resistant, which was exactly what I needed.

Ruby T. ★★★★★

The precision-ground shoulder rides smoothly in my drill jig, which is exactly what I needed for a consistent pivot point. The 18/8 stainless finish also gives me confidence these won't corrode in my damp workshop. Slightly pricier than zinc ones, but worth it for the tolerance.

Natalie T. ★★★★★

Used these as pivot axles for a small hinge project and the precision-ground shoulder made for a snug, wobble-free fit. The 18/8 stainless finish looks clean and should hold up well outdoors. They drive in smoothly with a hex key, no stripping or binding even after tightening down several. Exactly
