Customer Reviews (4.4 / 5 · 5 reviews)

Zoe M. ★★★★★

Needed some M6 bolts with a good grip length for a metal frame project, and the partial threading on these really simplifies alignment. The zinc coating looks even and should hold up fine against light moisture in the garage.

Scarlett H. ★★★★★

The unthreaded grip section on these M6 bolts made aligning my metal brackets a lot easier than with fully threaded ones. They all seated cleanly in the hex driver without any slippage. For the price, getting a full box of 200 is excellent value for a weekend project.

Nicholas ★★★★☆

Picked up a pack of these M6 bolts for a project needing that unthreaded grip section. The zinc plating seems even and should hold up well indoors. A solid value for the quantity you get, though the threads could be a touch cleaner.
