Customer Reviews (4.4 / 5 · 5 reviews)

Owen A. ★★★★★

The black oxide finish wiped clean easily and looks sharp on my fixture plates. Threads seated smoothly into tapped holes without any binding, and the nylon patch held them snug during a full day of vibration testing.

Aurora ★★★★★

The nylon patch is a nice touch—these held tight in my precision assembly without any loosening after a full day of vibration. The hex socket drive seated perfectly with my Allen key, and the black oxide finish looks clean and professional.

Daniel ★★★★★

The black oxide finish looks sharp and gives them a nice uniform color that's held up well in my workshop. I've used about sixty of them in jigs and fixtures so far, and the hex socket drive seats cleanly every time.
