Customer Reviews (5.0 / 5 · 5 reviews)

Jason ★★★★★

Needed a fully threaded option for a heavy-duty jig I'm building, and these M42s fit perfectly. The 120mm length gave me just enough grip through thick steel plates without bottoming out.

Ruby ★★★★★

The hex heads on these 120mm screws gave my socket wrench a solid grip without any slipping. They feel heavy and well-made for industrial fastening, exactly what I needed for mounting heavy equipment.

Miles ★★★★★

Threads started by hand without binding, even under the full torque of a 1-inch impact wrench. The 10.9 grade steel held up perfectly on a conveyor roller assembly I was repairing.
