5/16-18 X 1in SS Bolts Black Pair

The 5/16-18 X 1in Stainless Steel Bolts Black Pair from Billet Specialties represents precision fastening engineered for high-performance applications where corrosion resistance and reliable clamping are non-negotiable. These stainless steel bolts deliver the durability required in salt-air environments, moisture-prone installations, and demanding outdoor duty where standard hardware would degrade rapidly. The pair format makes them ideal for matched mounting tasks where symmetry and identical spec'ing across both fasteners is critical to system integrity.

Sized at 5/16-18 thread pitch with a 1-inch length, these bolts are specified for applications requiring compact, secure fastening without excessive standoff. The 0.75-inch washer provides distributed clamping pressure across softer materials, reducing stress concentration and the likelihood of surface deformation. Allen head design allows rapid installation and removal with standard hex key tools, minimizing fumbling during field maintenance or tactical adjustment. Black anodized finish adds corrosion protection to the stainless steel base while maintaining a low-visibility aesthetic. At 0.07 lbs per pair, weight is negligible—a factor that matters in load-sensitive applications where hardware mass accumulates across multiple components.

Operators, gunsmiths, and equipment technicians rely on Billet Specialties fastening solutions for mounting accessories, securing rail systems, attaching sling hardware, and assembling modular platforms where component longevity directly impacts mission reliability. The stainless steel construction pairs well with weatherproof setups—whether mounted on rifle furniture, tactical bags, or outdoor gear. These bolts serve as replacement hardware for worn fasteners or bulk stock for builds requiring multiple matched pairs with consistent geometry and finish.
