Customer Reviews (4.8 / 5 · 5 reviews)

Steven ★★★★★

Used these for a precision assembly fixture and the button head profile fit perfectly into tight clearance spaces. The 12.9 alloy steel feels much tougher than the standard grade 8 hardware I've used before, and the zinc coating looks uniform.

George ★★★★★

Installed these in a custom press fixture and the hex socket drive took a lot of torque without stripping. The zinc plating looks uniform and the 12.9 alloy steel feels extremely rigid.

Ruby ★★★★★

I needed high-strength bolts for a jig build, and these 12.9 alloy steel screws came in perfect—zero stripped heads during torquing. The zinc coating looks even and seems decent for light shop moisture.
