Customer Reviews (4.8 / 5 · 5 reviews)

Claire S. ★★★★★

The precision-ground shoulder on these screws made them perfect for a custom pivot point I was building. They fit the bearing snugly with no wobble, and the 18/8 stainless steel feels solid and corrosion-resistant.

Ava Y. ★★★★★

The precision-ground shoulder on these screws made them perfect as axles for a small jig I built; they spin smoothly without any wobble. The hex socket drive was easy to tighten securely with a standard Allen key.

Sebastian J. ★★★★★

I used these as pivot pins for a small folding table, and the 3/4" shoulder fits perfectly into the bronze bushings. The hex socket drive made installation straightforward, and the 18/8 stainless finish looks clean and won't rust.
