Abigail F. ★★★★★

The zinc plating on these M20 bolts held up perfectly during a wet outdoor assembly job, no rust after a week of rain. Used them to secure a heavy steel bracket to a concrete base, and the fully threaded length gave me plenty of grip. Solid fasteners for the price.

Eva F. ★★★★★

These M20 hex bolts fit perfectly into the flanges on my pump stand, and the zinc plating looks like it'll resist rust well in our humid shop. Threads were clean and sharp right out of the package, no binding at all during installation. Just what I needed for a solid mechanical joint.

Owen I. ★★★★★

The hex head on these M20 bolts fits my socket wrench perfectly, making assembly of my press frame much faster. The zinc plating looks clean and should hold up well in the shop, and the 10.9 grade gives me confidence in the strength.
