Customer Reviews (5.0 / 5 · 5 reviews)

Ellie I. ★★★★★

The hex socket drive made torquing these down in a cramped bracket genuinely painless, and the cup point bites into the shaft exactly as it should. 316 stainless gives me zero worry about rust in the damp garage, and at this count I'm set for a long time.

Nicholas D. ★★★★★

Used them to secure a small pulley on a custom build and the 316 stainless gave me peace of mind against rust. The hex socket drive made tightening in a cramped spot much easier than a standard hex key.

Ava ★★★★★

The cup point on these M4 set screws bites into metal firmly, and the 316 stainless finish looks clean. I used a full 500 in a batch of custom brackets, and every single one threaded smoothly without any burrs.
