Customer Reviews (4.8 / 5 · 5 reviews)

James O. ★★★★★

Used these on a heavy piece of shop equipment and the threading was clean all the way down, no binding during installation. Definitely sturdy enough for the job I had in mind.

Christopher ★★★★★

Installed these on a large hydraulic press repair job last week and the threads ran smooth all the way in. The 8-1/2 inch length was exactly what I needed for the stack-up, and the plain finish held up fine under the torque.

John R. ★★★★★

Used these for mounting a heavy gearbox to a frame and the partially threaded section made alignment a breeze. The alloy steel feels seriously tough, no bending or stripping even with a high-torque impact driver.
