Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn ★★★★★

Used these to rebuild a press at work and the hex head let me torque them down evenly with a socket—no rounding issues. The yellow zinc finish looks clean and should hold up better than plain steel.

Natalie ★★★★★

Had to replace some bolts on a hydraulic press, and these L9 alloy steel heads took the torque without stripping. The yellow zinc coating is a nice touch for resisting shop grime.

Eva B. ★★★★★

Picked these up for a jig fixture I’m building, and the yellow zinc finish on the Grade L9 alloy steel feels much more corrosion-resistant than the cheap hardware at the big box store. Full threading made them bite cleanly into the tapped hole without any binding, even with a socket driver.
