Customer Reviews (5.0 / 5 · 5 reviews)

Victoria G. ★★★★★

The zinc plating is holding up nicely on these—no rust after a couple of weeks in a slightly damp shop. The hex heads grab a wrench cleanly and the thread cut on all 600 feels consistent, which saved me a lot of fumbling.

Lucy ★★★★★

I needed a proper supply of M5 bolts for a small assembly project, and these class 8.8 steel ones drive in smoothly with a hex key without stripping. The zinc coating feels durable and the 600-count box will last me through many more builds.

Steven ★★★★★

The zinc plating looks even and consistent across all 600 pieces, and the hex heads fit my socket wrench without any wobble. Used about 80 of them on a steel frame assembly today, not a single stripped thread or seized bolt.
