Customer Reviews (4.6 / 5 · 5 reviews)

Chloe ★★★★★

Black oxide finish looks sharp and the threads cut cleanly with no chatter when I torqued them down on my jig fixture. The 3/4-10 size fits perfectly in the counterbore I machined, and all 25 in the pack had consistent depth on the hex socket. These are solid enough for heavy machinery work.

Zoe T. ★★★★★

The black oxide finish on these screws handled the oil in my press jig without any rust or mess, which was a relief. They threaded cleanly into the tapped holes and held firm with no stripping. Exactly the quality I was hoping for in a heavy machine repair.

Isabella Z. ★★★★★

I needed a strong fastener for a new press fixture and these cap screws threaded in smoothly with no binding. The black oxide finish feels durable and should resist rust well in my shop.
