Customer Reviews (4.8 / 5 · 5 reviews)

Andrew C. ★★★★★

Had to retorque these after the initial run-in, which I expected with L9 alloy steel, but once settled they haven't budged a bit even under heavy vibration. The hex heads grab a socket perfectly without any slipping.

Edward ★★★★★

Installed these on a heavy-duty press clamp and they threaded in smoothly with no binding. The yellow zinc finish is definitely tougher than the standard black oxide I usually get.

Daniel J. ★★★★★

The threading is clean and consistent all the way down, which made torquing these into place surprisingly smooth. The yellow zinc finish looks properly applied too, no flaking or uneven spots across the ten pieces.
