Customer Reviews (5.0 / 5 · 5 reviews)

Matthew ★★★★★

These bolts threaded smoothly into the m16 nut I tested them with, and the hex head gave my socket wrench a solid, no-slip grip. The class 10.9 rating gave me confidence for a heavy machinery frame I’m bolting together.

Evelyn I. ★★★★★

The yellow zinc coating is evenly applied with no bare spots, and the hex heads seated cleanly in my socket without stripping. Used them to bolt a heavy frame together and they drove in smooth with zero wobble.

Grace ★★★★★

Threads are perfectly clean and the 10.9 steel feels rock solid under a wrench, no stripped heads on any of the 25. Yellow zinc coating is a nice touch for shop work where a little oil or moisture shows up. These will be my go-to for heavy equipment mounts from now on.
