Customer Reviews (4.4 / 5 · 5 reviews)

Madison ★★★★★

Used these to secure some heavy brackets in my workshop, and the hex head made torquing them down with a socket effortless. The yellow zinc coating looks clean and seems like it will hold up well against moisture.

Samuel ★★★★★

The 40mm length is spot on for my engine mount brackets, and the zinc coating seems thick enough to resist rust. They seated smoothly with a socket, which saved me a lot of time on a repetitive job.

Nicholas ★★★★☆

Good threads, the class 8.8 steel feels solid and the yellow zinc coating looks like it'll resist rust well for indoor equipment. One minor thing: a couple screws had slightly uneven plating, but nothing that affects function.
