7/16-14 X 1-1/4" 杯端內六角止付螺絲 | 18/8 不鏽鋼 (100顆/包)

The hex socket drive made torquing these down in a tight spot a breeze, and the cup point really bites into the shaft without slipping. I’ve already used a dozen on a gear hub repair and they’ve held solid. The 18/8 stainless finish feels tough, no rust worries so far.

I needed a stainless set screw that wouldn't rust in a damp environment, and the 18/8 construction on these feels solid. The cup point bites nicely into the shaft without marring it too much, which is exactly what I wanted for a precise adjustment.

The hex socket drive made it easy to tighten these into a tight spot on my motorcycle frame. No stripping or slipping like with Phillips heads. Good solid feel for the price.
