Chevy Timing Cover Bolts

The MOROSO Chevy Timing Cover Bolts (Part No. 38590) is a Grade 8 steel fastener kit designed specifically for small-block and big-block Chevrolet V8 engines. This 10-piece set provides a reliable fastening solution for timing cover installation, ensuring secure and effective performance during engine operation.

Each bolt features a 1/4-20 inch thread, integral serrated face washer, and is zinc plated for corrosion resistance. The Grade 8 classification indicates that these bolts meet SAE J429 standards for tensile strength, which is critical for maintaining timing cover seal integrity under engine vibration and thermal cycling. The integral serrated face washer helps prevent fastener rotation and backing-out, addressing common issues in high-vibration environments.

Engine builders and restoration shops will benefit from this kit, as it provides matched fasteners that meet OEM specifications for geometry and strength. Using high-quality fasteners like these is essential to avoid oil leaks, loss of engine vacuum sealing, and potential catastrophic failures. This 10-piece set is an excellent choice for anyone looking to ensure the reliability and longevity of their Chevrolet V8 engine.
