Customer Reviews (4.8 / 5 · 5 reviews)

Hannah ★★★★★

Using these on a jig I'm building and the hex head bites well with a socket, no stripping so far. The 20mm length was exactly what I needed for this particular assembly and the zinc coating looks clean and uniform.

Julian ★★★★★

I needed a solid batch of M6 screws for a machine rebuild, and these 20mm ones fit perfectly with a socket driver. The hex heads gripped tightly without stripping, and the fully threaded design made alignment a breeze.

Victoria X. ★★★★★

The zinc plating on these M6 bolts looks factory-fresh and consistent across all 400 pieces, which saved me a trip to the hardware store. They threaded cleanly into my equipment frame without any binding or stripping.
