Customer Reviews (4.8 / 5 · 5 reviews)

Natalie U. ★★★★★

The yellow zinc coating looks great and should hold up in our shop environment. These 1"-8 threads seated firmly with a socket wrench on our press frame, no wobble or cross-threading at all.

Grace ★★★★★

These thread right in clean and the yellow zinc finish looks proper on my press rebuild. I've torqued them down good and the hex heads grabbed the socket without any stripping, so they're holding up as solid as I'd expect from a US-made alloy bolt.

Christopher ★★★★★

Finally found some 1"-8x4" bolts locally, and these worked perfectly for securing a press table. The hex head grabbed tightly with a socket, and the yellow zinc finish looks like it will resist rust well.
