If you're rebuilding the bottom end of a performance engine, you know that the connecting rod bolts are a critical stress point. Stock bolts can stretch or even fail under the increased cylinder pressures and RPMs that performance builds demand. That's where a well-built bolt like this Carrillo WMC series comes in. It's designed to handle the extra abuse.

This particular bolt is a 7/16 x 20 thread size with a 1.600 inch underhead length, making it a direct replacement for many popular performance applications. The H71/WMC7-1 head marking is Carrillo's way of identifying this specific bolt, ensuring you're getting the right part for your build. Carrillo is well-known for making strong internal engine components, and these bolts are no exception. They're made from robust materials to ensure they hold tight under extreme conditions.
