Manufactured from the same 8740 steel as ARP's High Performance Bolts, but with Wave Loc shank design. Wave Loc symetrical waves have an effective interference range of . 0005" to . 007" for proper cap alignment and fit. Stress risers formed by standard rod bolts in factory bolt holes are virtually eliminated.
Since 1968, ARP is the fastener of champions and the world leader in fastener technology.
