Customer Reviews (4.8 / 5 · 5 reviews)

Thomas ★★★★★

Finally, a fastener that doesn’t strip the hex socket when torqued down hard—these 12.9 alloy steel screws held my jig together perfectly. The 170mm length is just right for clamping thick plates without bottoming out.

Christopher V. ★★★★★

I needed long bolts for a custom fixture and these 12.9 alloy steel screws handled the torque without stripping. The partially threaded shank gave me just the right grip length for my assembly.

Emma ★★★★★

Finally found 170mm length M6 screws that actually work for deep clamping setups. The black oxide coating looks consistent across all 50 pieces.
