Customer Reviews (5.0 / 5 · 5 reviews)

Victoria ★★★★★

The cup point design really helps these set screws stay put when I’m tightening down components on a shaft for a small assembly. No more slipping or misalignment during install—these bite in nicely with the hex drive. Five stars from me.

Madison H. ★★★★★

These little set screws have a nice, sharp cup point that really bites into the shaft. The black oxide finish looks clean and professional, and the threads felt precise going in. Perfect for my jig build.

Adam ★★★★★

The hex socket drive made it easy to get these set screws torqued down in a tight spot. The black oxide finish on the alloy steel feels durable and seems like it will resist rust well for indoor use.
