Customer Reviews (4.6 / 5 · 5 reviews)

Ryan Y. ★★★★★

I needed something that wouldn't strip out when adjusting tight panels, and these hex socket drives let me apply serious torque without slipping. The zinc plating seems durable so far, and the 250-count package should last me through several projects.

David ★★★★★

The knurled cup point really digs in and holds firm, even on a slightly worn shaft. Installed a bunch of these on a jig today and not one slipped under load.

Sophia ★★★★★

The hex socket drive made snugging these into a tight bracket a breeze, and the knurled cup point grabs the shaft without stripping. Bag of 250 is plenty for the job I had, and the zinc plating still looks clean after a week of use.
