S/S Bolt Kit - 12pt. (5) 5/16-18 x 3.250

The S/S Bolt Kit - 12pt. (5) 5/16-18 x 3.250 from ARP is a professional-grade fastener assembly designed for tactical, military, and high-performance applications where reliability and precision are non-negotiable. This five-piece stainless steel bolt kit serves operators and armorers who demand fasteners capable of withstanding extreme conditions, vibration, and sustained operational stress.

Each bolt in this kit features a 12-point head design, which distributes load more evenly than standard 6-point fasteners and reduces the risk of rounding during installation. The 5/16-18 specification indicates a 5/16-inch diameter with an 18 threads-per-inch pitch, providing a fine thread engagement ideal for precision assemblies. At 3.250 inches in length, these stainless steel bolts resist corrosion and oxidation in harsh environments, whether salt-air, moisture-heavy, or chemically exposed settings.

Tactical armorers, weapons maintenance personnel, and equipment engineers rely on ARP fastener kits to ensure the integrity of their assemblies. The stainless construction maintains structural integrity without sacrificing magnetic properties where needed, making it suitable for various applications. This bolt kit meets the dependability expected in field-proven environments, ensuring that critical components are securely fastened.
