King Performance Crank Bolt – Made in the USA
Engineered for durability and precision, the King Performance Crank Bolt is proudly made in the USA using high-strength 17-4 Stainless Steel, heat-treated to H-900 condition for a Rockwell hardness of 40–44 RC. The bolt features precision-cut ‘J’ threads with a controlled root radius to prevent cracking under stress.
Designed for superior engagement, it offers 10mm more thread contact than most competing bolts. The bolt includes a robust 6.35mm thick retaining washer with a stepped center to ensure perfect alignment on the pulley hub and resist distortion under proper torque.
Also available in black zinc-coated 4340 Chromoly steel, this bolt fits with a 3/8" internal square drive and 1.000" external hex for versatile installation. Built for strength, reliability, and long-term performance.
Bolt has cut ‘J’ threads with a controlled root radius at the bottom. The radius keeps them from cracking.
