James ★★★★★

The cup point design really helped center the screw during assembly, and the black oxide finish looks great in my jig. These feel sturdy and well-made for the price.

Riley ★★★★★

The hex socket drive fit my driver perfectly without any wobble, and the cup point bit into the shaft firmly. These held a pulley in place on a lathe setup with zero slipping during use.

Eli J. ★★★★★

For the price of this pack, these are exactly what I needed to hold a collar in place on a lathe. The hex drive made tightening them down simple without stripping.
