Customer Reviews (5.0 / 5 · 5 reviews)

Abigail N. ★★★★★

The yellow zinc finish looks great on these and held up fine under the wrench. I’ve used a lot of 3/4” cap screws for equipment repairs, and the PFC9 alloy steel feels noticeably tougher than the standard stuff I’ve grabbed before.

Scarlett ★★★★★

These bolts drove in smooth with a socket, no binding at all. The yellow zinc coating looks like it'll resist rust, and given they're US-made, I'm confident they'll hold up on the press.

Leo T. ★★★★★

Threaded these into a heavy press frame and the hex heads seated perfectly with a wrench—no stripping or wobble. The PFC9 alloy feels solid, and the yellow zinc coating hasn't shown any wear after a week of use.
