M20-2.5 X 55mm Parafusos de cabeça sextavada | Aço classe 10.9 liso | Roscado total (20 / Pkg.)

These M20 cap screws were exactly what I needed for a heavy-duty jig on my press. The class 10.9 rating paired with a full thread gives excellent grip under high torque, and a 20-pack keeps extra on hand.

My torque wrench clicked off cleanly at spec on all twenty of these, and the class 10.9 hardness means I didn’t have to worry about stripping the threads during a tight flange repair. The hex heads have that dry, matte finish that grips a socket without slipping, and the 55mm length gave just enough

The fully threaded length is exactly what I needed for a custom jig, and the hex head seated well with a standard socket. Only gripe is the plain finish shows scuffs quickly after a couple of wrenches, but the 10.9 steel feels solid for the price.
