S/S Starter Bolt Kit 6pt.

The ARP Stainless Steel Starter Bolt Kit 6pt is a precision fastener solution engineered for high-performance automotive and engine applications. This pair of stainless steel hex head bolts, 4.660 inches in length, delivers the corrosion resistance and tensile strength demanded in performance engine builds, restoration work, and critical mechanical assemblies where OEM fasteners fall short.

ARP is recognized for producing fasteners that meet or exceed aerospace and motorsport standards. The polished stainless construction of this starter bolt kit resists oxidation and corrosion in harsh environments—particularly valuable for builders working with vintage GM platforms or applications exposed to moisture and salt. The 4.660-inch length and 6-point hex head geometry provide reliable engagement with standard fastener tools while maintaining the structural integrity required for engine startup loads. Each bolt in the pair is manufactured to tight tolerances, ensuring consistent clamping force and eliminating the variability common in lower-grade fasteners.

This kit serves restoration shops, performance engine builders, and mechanics upgrading GM engine blocks to fasteners that will outlast the original hardware. The two-bolt pair format allows replacement of failed or corroded factory fasteners without excess inventory. Stainless steel bolts of this specification are essential when reassembling engines destined for long-term service, particularly in applications where vibration and thermal cycling demand fasteners engineered beyond commodity grade standards.

For builders prioritizing durability and corrosion resistance in starter mounting and related engine assembly work, the ARP stainless steel starter bolt kit delivers the material science and precision finish that separates professional-grade builds from routine service replacements. The polished finish offers both aesthetic clarity and functional protection against environmental degradation.
