Henry G. ★★★★★

I needed these for a jig I was building, and the hex socket drive made installation a breeze. The black oxide finish seems tough and should hold up well in my shop.

Emma H. ★★★★★

The knurled cup point gives a really solid grip on the shaft, and the black oxide finish seems like it'll resist rust well. I used a dozen on a jig I'm building and every one seated perfectly without stripping.

Claire T. ★★★★★

The hex socket drive made seating these in a tight spot effortless, and the black oxide finish gives them a clean, uniform look against the steel shaft. The knurled cup point held firm after a full day of vibration testing on the coupling, so I’m ordering another pack for the next job.
