Austin Mini Competition Crankshaft Front Pulley Bolt

This high performance crankshaft pulley bolt with 'rolled' threads is nearly 20% stronger than cut threads, and has an engagement of 1.0" compared to a stock length of 0.75". This added engagement will fit all crankshafts and provide a great deal of enhanced protection from loosening. The bolt head is also drilled for safety wire, AND features a 3/4 inch hex head that CAN be driven with a socket WITH the lower radiator support installed- unlike the 1 5/16 stock unit!
