Timing Cover Fasteners 10pk

The ALLSTAR PERFORMANCE Timing Cover Fasteners 10-Pack (ALL 99390) is a precision stainless steel bolt kit engineered for Small Block Chevy engine builds. This set of 10 allen head fasteners delivers the corrosion resistance and mechanical reliability required in demanding engine assembly and rebuild applications where timing cover security is critical to engine integrity.

Each fastener in this timing cover bolt kit is manufactured from stainless steel, providing superior resistance to oxidation, salt air exposure, and prolonged moisture contact compared to standard zinc-plated hardware. The allen head design enables precise torque application using standard hex key tools, reducing fastener slippage during installation and allowing repeatable, controlled tightening to manufacturer specifications. For Small Block Chevy applications, proper timing cover bolt tension is essential—under-torqued fasteners risk coolant seepage and oil weeping, while over-torqued bolts can strip threaded holes in aluminum casting. Stainless steel's material properties help mitigate galling during repeated assembly and disassembly cycles common in engine development and maintenance workflows.

This 10-piece kit serves engine builders, automotive technicians, and serious enthusiasts performing Small Block Chevy rebuilds, performance upgrades, or restorations. Whether assembling a stock replacement engine, modifying a carburetor intake manifold setup, or completing a full bottom-end refresh, sourcing the correct fastener spec from the outset eliminates mid-project sourcing delays. The compact 10-pack delivers the exact quantity needed for a complete timing cover installation without excess inventory.

Small Block Chevy engines remain the benchmark platform for hot rod, street machine, and performance vehicle builds. Using grade-appropriate fastening hardware—particularly stainless steel in applications exposed to fluid contact—protects long-term engine reliability and finish appearance. ALLSTAR PERFORMANCE specializes in engine fastening solutions that meet or exceed OEM standards for Small Block applications.
