Customer Reviews (4.8 / 5 · 5 reviews)

Stella W. ★★★★★

The yellow zinc coating on these bolts seems really durable, and the threads were clean right out of the package. Hand-tightened them easily before torquing down my lathe base, and they held perfectly without any stripping.

Adam P. ★★★★★

Used these to bolt down a heavy press in my shop and the threads cut cleanly without any binding. The 8-inch length and partial threading made it easy to get a solid grip with a socket.

John X. ★★★★★

Wasn't sure about the partially threaded design at first, but it made alignment on my heavy equipment frame much easier than fully threaded bolts would have. The yellow zinc coating looks consistent and should hold up well in my shop.
