Henry ★★★★★

Installed a full set of these in a metalworking jig last week and the hex socket drive made tightening them so much easier than using a Phillips. The zinc plating feels consistent and none have stripped under moderate torque yet.

Victoria W. ★★★★★

Roughly two weeks of daily use in my jig setup and these haven’t stripped or corroded a bit, the zinc plating holding up nicely under shop dust. The 12.9 alloy steel feels genuinely sturdy for the price, though I wish they included a spare hex key in the bag.

Isabella B. ★★★★★

The hex socket drive grips my Allen key perfectly, no stripping even after torquing them down on a fixture plate. For a bulk box of 600, the zinc finish looks uniform and none arrived with damaged threads.
