Customer Reviews (4.8 / 5 · 5 reviews)

Adam U. ★★★★★

The partially threaded design made aligning the mounting bracket way easier than dealing with fully threaded rods on my press rebuild. Grade L9 hex heads seated cleanly with a socket, and all twenty cut threads without any galling.

Victoria ★★★★★

The yellow zinc coating on these bolts looks great and resists rust well, and the partially threaded shaft gave me plenty of grip for my equipment mount. Used a 1-1/8" socket and they seated perfectly in pre-drilled holes with no stripping.

John ★★★★★

Put these on a heavy press fitting yesterday—the partial threading made aligning the nut a breeze without binding. The hex head seated perfectly with a standard socket, and the yellow zinc coating seems like it'll hold up well in our shop environment.
