Owen X. ★★★★★

I used these for building a jig in my shop and the black oxide finish held up well against the oily wood. The hex socket drive made them easy to install in tight spots.

Matthew M. ★★★★★

The nylon patch on these screws is a nice touch for holding tight under vibration, and the black oxide finish looks clean on my jig setup. They threaded smoothly into tapped holes without any binding.
