Customer Reviews (4.8 / 5 · 5 reviews)

Thomas N. ★★★★★

The hex socket drive fit my torque wrench perfectly, making install on a die fixture effortless. At 180mm long and partially threaded, these bolts grabbed deep into the assembly without any wobble.

Nicholas ★★★★★

Installed these in a milling fixture where standard cap screws kept loosening; the 12.9 alloy steel holds torque noticeably better. The partial threading seated perfectly into the tapped hole without binding. Solid upgrade for any heavy tooling setup.

Adam Z. ★★★★★

I needed longer bolts for a heavy jig build, and these M20's 180mm length was exactly what I was after. The zinc plating looks clean and consistent, and they threaded smoothly into tapped holes without any binding.
