S/S Bolt Kit - 6pt. (5) 3/8-16 x 2.250

The S/S Bolt Kit - 6pt. (5) 3/8-16 x 2.250 is a precision fastener assembly engineered for high-performance tactical and motorsport applications where reliability and load-bearing capacity are non-negotiable. Designed for operators, armorers, and engine builders who demand aerospace-grade materials and consistent tensile strength, this stainless steel bolt kit provides the structural integrity required in demanding environments. Whether securing critical firearm components, assembling tactical equipment, or building high-performance engines, this five-piece kit delivers proven durability under extreme conditions.

Each bolt in this kit features a 3/8-inch diameter with a 16 threads-per-inch (TPI) specification and a 2.250-inch length, providing optimal engagement and load distribution in precision assemblies. The 6-point head design—a hallmark of professional-grade fasteners—offers superior grip geometry compared to standard hex fasteners, reducing strip-out risk during installation and removal cycles. Manufactured from stainless steel, these bolts resist corrosion, oxidation, and temperature-induced degradation, ensuring consistent performance in saltwater, humidity-heavy, and high-heat environments. The five-piece configuration allows for modular repairs or replacement without excess inventory, a practical approach favored by field-deployed teams and precision gunsmiths.

This bolt kit is ideal for law enforcement armorers, military maintainers, and tactical equipment builders requiring OEM-spec or aftermarket firearm assembly and repair. The 3/8-16 x 2.250 dimensions are commonly found in AR platform upper and lower receiver assemblies, precision rifle builds, and heavy-duty equipment mounting systems. Installation is straightforward using standard metric or inch-pattern wrenches and torque-calibrated tools; proper torque specifications should be referenced for your specific application to ensure load security and prevent over-tightening. Keep a spare kit on hand for field repairs, training exercises, or component upgrades—the compact 0.44 lb weight makes storage and deployment effortless.
