Charlotte P. ★★★★★

Used these on a custom fixture where I torqued several to spec—the hex socket drive seated cleanly without stripping, and the zinc plating looks uniform across all 100. For 12.9 alloy at this price per piece, they’re a solid pick for anything load-bearing.

Joseph ★★★★★

Needed some hardened bolts for a jig I was building, and these 12.9 alloy screws handled the torque perfectly. The flat head sat flush in the countersunk hole, and the zinc coating looks clean.

Steven ★★★★★

The socket drive on these M8s grips the hex key with zero wobble, and the zinc plating looks clean right out of the package. Threads are precise enough that they seated smoothly into my jig’s tapped holes without any binding. Just the right mix of hardness and finish for a 12.9-grade bolt.
