Customer Reviews (4.2 / 5 · 5 reviews)

Henry ★★★★★

I needed new fasteners for a precision assembly fixture, and the hex socket drive made tightening them in tight spots much easier. The black oxide finish looks clean and seems durable for repeated use.

Sebastian D. ★★★★★

The black oxide finish on these 1/4-20 screws is flawless and really helps them resist rust in my shop. I used a dozen for a jig rebuild and every single one seated perfectly without any burrs.

Daniel ★★★★☆

The black oxide finish on these screws handled my jig project without any galling, and the hex drive seated perfectly with my Allen key. Only wish the package included a couple extra spares in case I drop one.
