Customer Reviews (4.6 / 5 · 5 reviews)

Thomas ★★★★★

I needed some quality set screws for a project, and these fit perfectly in tight spaces thanks to the hex socket drive. The zinc plating looks clean and should resist rust well.

Charlotte G. ★★★★★

The knurled cup point really bites into the shaft without stripping, and the hex socket let me torque them down in a cramped spot where a wrench wouldn’t fit. Zinc plating looks clean and even across all 100 pieces.

Lucy P. ★★★★★

Perfect alignment for my indexing fixture — the knurled cup point really digs in and won't let go under vibration. Installed them with a hex key in a tight spot and they seated beautifully.
