Customer Reviews (4.8 / 5 · 5 reviews)

Sophia ★★★★★

Finally, some M16 bolts that actually fit a standard 22mm socket without any chatter. The 40mm length was perfect for securing the base plate on my press, and the yellow zinc finish looks better than I expected against the black steel.

Emma B. ★★★★★

The threads are clean and the yellow zinc coating is evenly applied with no bare spots across all 50 pieces. I used a socket wrench on a few and the hex heads held up without rounding, which is what I needed for a quick machinery repair job.

Lucy ★★★★★

I was pleasantly surprised by the uniform thread quality on all fifty pieces; each one threaded smoothly into the tapped hole without any binding. The hex head gave my socket a solid grip, making installation on our conveyor line much faster than I expected.
