Owen W. ★★★★★

The cup point bit on these screws really digs in and stays put without stripping. I've been using them to lock down a heavy bracket on my milling machine, and they've held the adjustment perfectly. Good value for a pack of 50.

Ryan ★★★★★

These are exactly what I needed for a high-torque adjustment on a jig I built; the hex socket drive makes tightening them in tight spots a breeze. The cup point bit into the metal firmly without slipping.

Evelyn P. ★★★★★

The zinc plating on these screws looks really clean and held up perfectly while I was tightening them in a tight spot. The cup point tip seated nicely without slipping. I’ve already used half the pack for a project and everything feels solid.
