Copper Exhaust Nuts m8 12mm across flats, kit of 8

Use these nuts on exhaust manifold and heater box studs, all models. 12mm across the flats for easier tool access (most m8 nuts are 13mm), and the locking ring helps prevent loss of torque on the fastener. Use with our 1200º copper anti-sieze paste for foolproof exhaust connections. Made by Febi Germany.

Sold in packs of eight (8).
