Bulk Header Bolts (100) Pieces by Mr. Gasket provide the fastening reliability that law enforcement, military personnel, and motorsport enthusiasts demand when assembling or maintaining high-performance equipment. These 3/8-16 inch thread bolts are engineered for applications where consistent tensioning and secure retention are non-negotiable—from exhaust manifold assembly to equipment mounting systems. The 100-piece bulk configuration eliminates the need for multiple orders and ensures inventory availability for shop environments, armorer stations, and field maintenance operations.
Each fastener features a 3/8-16 inch thread pitch with a 1 inch length and traditional hex head design for reliable wrench engagement and consistent torque application. The black oxide finish provides superior corrosion resistance and durability in demanding environments—critical for equipment exposed to harsh weather, moisture, and thermal cycling. Steel construction delivers the tensile strength required to maintain bolt preload under vibration and stress, preventing loosening over time. This finish also reduces light reflection, making it ideal for tactical and military applications where operational discretion is essential.
Armorers, maintenance technicians, and equipment specialists benefit most from the bulk 100-piece format, which supports large-scale assembly projects and reduces per-unit cost. These bolts are compatible with any application requiring 3/8-16 inch fastening—including header assembly, equipment mounting, and structural attachment systems. Installation is straightforward: insert the bolt through pre-drilled holes, apply appropriate torque using a standard wrench or socket, and verify tension regularly to maintain operational integrity. Recommended for professional and institutional use where quality fastening materials directly impact equipment reliability and mission success.
