They have a tensile strength of 190

with threads rolled after heat treat to ensure the optimum fatigue strength

while the bolt kits come with washers

reciprocating and valve train components

The importance of pressure plate bolts in a racing or hi-performance street application cannotbe emphasized nearly enough

What’s more

Following heat-treat

and -6 thru -20 O-ring sizes

ARP studs are thread rolled after heat-treat

ARP 12-point nuts are manufactured in thick wall versions for optimum strength and rigidity and thin wall versions for applications with limited space requirements

All Pro Series head bolts have areduced wrenching hex or 12-point head and wide area flange to permit the use of larger diameter valve springs and eliminate theneed for valve train removal during cylinder head retorquing

but the results are well worth the extra effort
