Customer Reviews (4.8 / 5 · 5 reviews)

Jacob G. ★★★★★

The #4-48 threads cut cleanly into my jig fixture without any binding, and the black oxide finish didn’t flake off when I torqued them down. For a fifty-pack at this price, these are exactly what a precision assembly needs.

Hazel G. ★★★★★

These black oxide screws fit perfectly into my jig setup without any binding. The hex socket drive made installation quick with a standard Allen key, and the 50-count pack will last me through several projects.

Claire F. ★★★★★

Finally found a #4-48 fastener that doesn't strip when I tighten it down for jig assembly. The socket drive engages perfectly every time.
