Customer Reviews (4.0 / 5 · 5 reviews)

Eli ★★★★★

Installed these in a jig I’m building for work and they seated perfectly with no binding. The hex drive held up fine with my torque wrench, and the zinc coating looks clean and even.

Adam ★★★★☆

These are holding up well on my jig build so far, and the zinc plating has a nice even finish. Took a star off because a couple of the hex sockets felt slightly tight on the driver, but the 12.9 hardness gives me confidence in them.

Isabella B. ★★★★☆

Threaded all the way down, these held tight in a heavy-duty fixture without any slippage. The zinc plating looks clean and even, and the hex drive makes them easy to seat with just an Allen key. Only wish the package came with a couple extra spares for future tweaks.
