How to install a copper sealing washer for M12 fasteners?
Place the copper sealing washer between the fastener head and the mating surface. Tighten to the recommended torque for M12 bolts. Copper deforms slightly under compression, filling surface irregularities. Avoid over-tightening, which can extrude the washer and reduce sealing effectiveness.
