Customer Reviews (4.4 / 5 · 5 reviews)

Abigail S. ★★★★★

I was pleasantly surprised by how cleanly the hex socket drive engaged with my wrench—no stripping or slipping during assembly on my latest jig. The black oxide finish gives them a nice, uniform look that resists wear well.

George ★★★★★

The nylon pellet in these screws is a lifesaver—they hold fast under vibration without loosening on my jig fixtures. Black oxide finish looks clean and the hex socket drive fits snugly every time.

Riley Y. ★★★★☆

These are perfect for mounting some brackets I made for my shop jigs. The black oxide finish looks clean and the hex socket drives snugly without stripping. Only wish they came in a slightly smaller quantity for smaller projects.
