S/S Starter 6pt Bolt Kit 10mm x 4.470 UHL

The S/S Starter 6pt Bolt Kit 10mm x 4.470 UHL from ARP is a precision-engineered fastening system designed for demanding applications in tactical, military, and high-performance engine builds. This stainless steel bolt kit addresses the critical need for reliable, corrosion-resistant hardware in environments where vibration, thermal cycling, and mechanical stress demand superior clamping force and longevity.

The 10mm diameter with a 4.470-inch under-head length (UHL) specification provides substantial clamping surface and load capacity essential for high-stress applications. Six-point head geometry offers superior wrench engagement and reduced cam-out risk compared to conventional fasteners—a critical advantage when working in tight spaces or under field conditions where equipment damage cannot be tolerated. Stainless steel construction resists corrosion, oxidation, and salt-environment degradation, ensuring long-term reliability in storage, transportation, and deployment scenarios.

The precision threading and manufacturing tolerances inherent to ARP fasteners guarantee consistent torque values and predictable preload characteristics, eliminating the guesswork in critical assembly work. Whether you're assembling critical components in a rifle platform, securing engine internals, or constructing tactical equipment, this kit delivers the fastening integrity that field operators and gunsmiths have come to expect from ARP's reputation for manufacturing excellence.
