Customer Reviews (4.6 / 5 · 5 reviews)

Matthew H. ★★★★★

The black oxide coating on these screws gives them a nice grip feel during installation, and they threaded smoothly into my jig fixture without any binding. Used a full pack on a tooling setup and every single one seated perfectly.

Claire Q. ★★★★★

Used a handful of these to rebuild a jig at work and the hex drive seated perfectly with no cam-out. The 5/16-24 threads cut cleanly into the tapped holes, which is exactly what I needed for precision assemblies.

Hazel ★★★★★

Needed these for a jig I'm building and the 5/16-24 thread pitch is exactly right. The black oxide finish feels solid and should hold up well in the shop.
