Customer Reviews (4.8 / 5 · 5 reviews)

Christopher B. ★★★★★

Used these to secure a jig on my drill press and the hex head made tightening with a socket wrench effortless. The yellow zinc coating feels durable and hasn't shown any rust after a few months in a damp shop.

Emily ★★★★★

Finally got these to replace some worn out bolts on a heavy assembly press and the class 8.8 rating seems solid so far. The yellow zinc coating looks consistent and they thread smoothly into existing nuts.

Brian ★★★★★

I needed a long M4 bolt for a custom jig, and the 40mm length paired with the hex head made it easy to tighten in a tight spot with just a socket driver. The yellow zinc coating seems to resist rust well so far.
