S/S Bolt Kit - 12pt. (5) 5/16-18 x 2.250

The ARP Stainless Steel Bolt Kit – 12pt (5) 5/16-18 x 2.250 delivers precision-engineered fasteners engineered for critical applications where material integrity and corrosion resistance are non-negotiable. This five-piece set features 5/16-18 threads with 2.25-inch length and polished stainless construction, making it suitable for assembly work, equipment repair, and restoration projects where standard hardware fails under demanding conditions.

Each bolt uses a 12-point head design that accepts multiple drive types, reducing the risk of rounding and increasing accessibility in tight spaces. The 5/16-18 thread specification delivers adequate clamping force for mid-range fastening tasks, while the 2.25-inch length accommodates components requiring deeper penetration without excessive overhang. Polished stainless steel offers superior corrosion resistance compared to zinc-plated alternatives, particularly in moisture-prone, salt-air, or chemically aggressive environments. ARP's quality standards ensure consistent dimensional tolerance and reliable performance across the entire set.

This kit serves technicians, builders, and operators managing equipment maintenance, chassis assembly, or component replacement where corrosion concerns limit standard fastener options. The universal design enables application across automotive rebuilds, marine environments, industrial equipment repair, and custom assembly projects. Having a dedicated set of precision stainless bolts eliminates downtime from rust-compromised fasteners and ensures long-term reliability in challenging operational conditions.

ARP stainless fasteners maintain material consistency and dimensional accuracy that standard commodity hardware cannot guarantee. The five-piece configuration allows for complete fastening solutions or emergency backup inventory in field kits and toolboxes.
