S/S Bolt Kit - 12pt. (5) 1/4-28 x .515

The ARP S/S Bolt Kit - 12pt. (5) 1/4-28 x .515 is a precision fastener set engineered for critical applications in tactical, firearms, and military equipment assembly. This five-piece stainless steel bolt kit is designed for shooters, gunsmiths, and tactical professionals who demand reliable, corrosion-resistant hardware for receiver builds, scope mounts, rail systems, and aftermarket component installation. Whether you're assembling a precision rifle, upgrading tactical gear, or maintaining law enforcement equipment, quality fasteners are non-negotiable—inferior hardware introduces failure points where reliability cannot be compromised.

Each bolt in this kit features a 1/4-28 thread pitch with a 0.515-inch length and a 12-point head design that provides superior grip and reduced cam-out compared to six-point alternatives. The stainless steel construction with polished finish delivers exceptional corrosion resistance in harsh field conditions, moisture-heavy environments, and extended storage—critical for tactical platforms exposed to salt spray, humidity, or chemical solvents. The 12-point head geometry is ideal for universal applications where consistent torque application and secure fastening are essential; the increased contact points distribute load more evenly than standard fasteners, reducing the risk of stripping or bolt failure under operational stress.

This bolt kit is essential for AR platform builds, precision rifle assembly, optics mounting, handguard and rail installation, and general tactical gear customization. Law enforcement armorers and military small-arms technicians rely on ARP fasteners for duty weapon maintenance and field repairs where quality standards are non-negotiable. The compact five-piece set (0.11 lbs) fits easily in any tool kit, maintenance pack, or gunsmith station, making it practical for range days, deployments, or professional service work. Verify thread pitch and bolt length compatibility with your specific application before installation; the 1/4-28 specification is universal across most AR-15 platforms and tactical equipment, but always match fastener dimensions to your receiver or mounting interface.
