Scarlett T. ★★★★★

The 12.9 alloy steel is noticeably tougher than the generic 8.8s I’ve handled, and the black oxide finish gave them a clean, uniform look straight out of the package. Threaded portion is just right for clamping down a 60mm fixture plate without bottoming out.

Robert Z. ★★★★★

Tore a thread on a jig last week and these came to the rescue—the 12.9 alloy steel feels rock solid, and the partial threading gave just the right grip without bottoming out. Black oxide finish looks clean too, no smudges after a day in the shop.

Adam ★★★★★

The hex socket drive seated perfectly on my Allen key, and the 12.9 alloy steel feels rock-solid. I used them to secure a jig on my mill table and the partial threading gave just the right grip for clamping. These are going to be my go-to for precision fixtures from now on.
