Customer Reviews (4.6 / 5 · 5 reviews)

Michael L. ★★★★★

These bolts fit perfectly in my socket wrench and the zinc coating looks clean and consistent across all 400 pieces. I used them to secure some heavy brackets and the class 8.8 rating gave me confidence in the hold.

Alexander ★★★★★

The hex drive on these M6 bolts fits my socket perfectly, making installation quick. For a hardware pack, the zinc plating looks clean and the threads are consistent across all 400 pieces. It's a solid value when you need a large quantity for repetitive assembly jobs.

James R. ★★★★★

These M6 bolts are exactly what I needed for mounting a conveyor guard. The Class 8.8 rating gives me confidence they'll handle the vibration, and the zinc plating looks clean and corrosion-resistant.
