Customer Reviews (4.6 / 5 · 5 reviews)

Jason ★★★★★

These cup point screws fit perfectly into the tapped holes on my shaft assembly, and the black oxide finish seems like it'll resist corrosion well. The hex socket drive gave me a clean, secure grip without any stripping.

Hannah P. ★★★★★

The hex drive on these set screws bites perfectly without stripping, even when torqued down tight in a hardened steel shaft. I used them to secure a small gear and they haven't budged a bit. Exactly what I needed for a precise mechanical assembly.

Joshua ★★★★★

These set screws have a nice sharp cup point that grips the shaft much better than cheaper brands I've tried. The black oxide finish seems durable and they threaded in smoothly without any binding.
