Copper Flashed Nut Flanged M8 x 1.25 x 13mm Hex 5pc

A pack of M8 x 1.25 pitch x 13mm Hex flanged nuts for use with exhaust manifold studs. The copper flashing acts as anti-seize coating and helps to eliminate seizure on the manifold studs, with the flanged base allowing for the pressure to be distributed over a greater contact area.
