Customer Reviews (4.6 / 5 · 5 reviews)

Riley I. ★★★★★

The hex socket drive grabbed my Allen key perfectly even in a cramped spot, and the cup point bit into the shaft without stripping. All 100 pieces looked clean and consistent, threads were sharp out of the box. Exactly what I needed for locking down a pulley.

Ella R. ★★★★★

I needed a set screw that could handle repeated adjustments in a tight motor assembly, and the hex socket drive on these made it easy to get a solid bite without stripping. The alloy steel feels tough and the threads matched my tap perfectly.

John ★★★★★

The cup point tip seated perfectly in my soft aluminum project without stripping or galling, which was a relief with these small fasteners. They're the right length for 1/4" plate and the hex socket drive gave me good control with just a 3/16" bit.
