S/S Bolt Kit - 12pt. (5) 3/8-16 x .500

The S/S Bolt Kit - 12pt. (5) 3/8-16 x .500 is a precision fastening solution engineered for tactical, military, and high-reliability applications where component integrity is non-negotiable. This five-piece stainless steel bolt set is designed for shooters, armurers, and equipment specialists who demand corrosion-resistant hardware for critical assembly work. Whether you're building a custom rifle platform, maintaining mil-spec equipment, or upgrading firearm components, quality fasteners are the foundation of safe, repeatable performance.

Manufactured by ARP (Advanced Racing Products), a trusted supplier of premium fastening solutions, this bolt kit features full stainless steel construction that resists rust, corrosion, and chemical degradation in field or storage conditions. The 12-point head design provides multiple contact points for wrench engagement, reducing the risk of rounding or stripping during installation or removal—a critical advantage in tactical builds where tools may be limited or conditions austere. The 3/8-16 thread pitch and .500-inch length specification make these bolts suitable for precision firearm assemblies, rail systems, and accessory mounting where dimensional accuracy directly impacts reliability and zero retention.

Law enforcement armorers, gunsmiths, and military personnel benefit from the versatility of this five-piece kit for bench work, field repairs, and component assembly across multiple platforms. The modest 0.2-pound weight and compact dimensions make this kit portable and practical for kit bags, mobile armorer setups, or maintenance stations. Before installation, verify thread compatibility with your specific application and follow manufacturer torque specifications for your firearm or equipment to ensure proper clamping force and long-term reliability.
