Customer Reviews (4.4 / 5 · 5 reviews)

Ava D. ★★★★★

The 18mm length was exactly what I needed for securing a heavy bracket, and the full threading made it easy to get a tight fit. The yellow zinc coating looks tougher than I expected from hardware at this price point.

Riley ★★★★★

These hex bolts drove in smoothly with a socket wrench, and the yellow zinc coating looks clean and consistent across all 400 pieces. For the price per pack, the Class 10.9 strength feels like a solid choice for mounting brackets.

Alexander ★★★★★

Picked up a pack of these M6-1 x 18mm hex head cap screws for assembling a small frame I’m building, and the Class 10.9 steel with yellow zinc finish feels really sturdy. The fully threaded shaft made it easy to get a tight, secure hold without any stripping.
