Moroso 38590 Timing Cover Bolt for Chevy | Cadmium-Plated Grade 8, Serrated Washer, 10-Pack

Overview

Meet the Moroso 38590 timing cover bolt, purpose-built for Chevy engines. Designed for a precise fit, these bolts pair a 1/4"-20 hex head with a cadmium-plated Grade 8 steel body, delivering a robust component that stands up to engine bay vibrations and heat exposure.
