Customer Reviews (5.0 / 5 · 5 reviews)

Violet T. ★★★★★

I needed to secure a heavy-duty sprocket, and these set screws held fast after torquing them down with a hex key. The zinc plating looks clean and should resist rust well. The cup point really digs in and keeps everything locked tight.

Emma ★★★★★

The cup point bites into the shaft really well, so there's no slipping even under heavy vibration. Zinc plating looks clean and the threads ran smooth without any binding. These are going to hold up fine for the price.

Riley ★★★★★

The hex socket drive made tightening these in a cramped spot a breeze, and the cup point held firm on the shaft without any slipping. Zinc plating looks clean and even across all 100 pieces, so no rust worries so far.
