The ARP S/S Bolt Kit - 6pt. (5) 5/16-18 x 3.000 is a professional-grade stainless steel fastener set engineered for high-reliability tactical, military, and industrial applications where corrosion resistance and structural integrity are non-negotiable. This five-piece kit supplies exactly what mission-critical assembly requires: premium fasteners that perform under stress, environmental exposure, and repeated cycles. Whether securing engine components, firearm accessories, or load-bearing structural elements, these bolts deliver the uncompromising durability that law enforcement and military personnel depend on.
Each bolt in this kit features a 5/16-18 thread pitch, 3-inch length, and a 3/8-inch hex head—specifications that align with standard SAE fastening protocols and ensure compatibility with common socket and wrench sizes used in field maintenance. The stainless steel construction with polished finish provides superior corrosion resistance compared to standard steel, making these bolts ideal for environments where salt spray, moisture, and temperature cycling would degrade inferior fasteners. The 6-point hex head geometry distributes load more evenly across fastening surfaces than 12-point alternatives, reducing the risk of stripping during installation and removal—a critical advantage in high-stress tactical environments where equipment reliability directly impacts operational success.
Operators, armorers, and maintenance technicians who service AR-pattern rifles, precision rifles, optic mounts, and modular tactical systems will recognize the universal value of this kit. The 5/16-18 x 3.000 specification covers common applications including upper receiver assembly, handguard attachment, scope mount bases, and accessory rail installations. Weighing just 0.46 lbs, this compact five-piece set fits easily into field repair kits or maintenance bags, ensuring that replacement fasteners are always available during range operations, deployment, or equipment modification. Stainless steel bolts of this specification resist galling and seizing, a particular advantage when disassembly occurs in demanding field conditions where corrosion or contamination may have compromised original fasteners.
