Holden Timing Cover Water Pumpbolt Kit 8740 308 253 V 8 Black 12 Point Aeroflow - Af 37-1629

when installing a new timing cover and water pump it is recommended to upgrade your mounting bolts. These timing cover and water pump bolts are made from chrome moly 8740 for strength. They are coated in a black oxide finish for protection and long-lasting durability. Each bolt features a compact 12-point head which is ideal for use where space is minimal on most aftermarket water pumps and timing covers compared to the factory bolts with a larger head. Each set includes thick flat washers for optimum clamping pressures to ensure a sure seal.
