Grace S. ★★★★★

Black oxide finish looks sharp and held up fine in my damp garage, no rust after a few weeks. These jam nuts thread on smoothly and the 3/8"-24 pitch matched my studs perfectly. Nice to have a full box of 1000 so I never run out mid-project.

George Q. ★★★★★

Perfect for locking down adjustments on my lathe. The black oxide finish looks clean and the hex heads grip firmly without stripping. A full thousand-pack means I won't run out anytime soon.

Matthew W. ★★★★★

Got these to secure my studs on a milling fixture, and the black oxide finish made them easy to distinguish from standard nuts. The hex head fits my wrench perfectly, and having a full thousand means I won't run out mid-project.
