Bolt Kit - 6pt. (5) 5/16-18 x 5.000

The Bolt Kit - 6pt. (5) 5/16-18 x 5.000 from ARP is a precision fastener set engineered for critical structural and mechanical assemblies where reliability under load is non-negotiable. Whether securing engine components, frame assemblies, or tactical equipment platforms, this hex socket bolt kit delivers the clamping force and repeatability demanded by law enforcement, military, and industrial technicians. The five-piece configuration provides practical coverage for rebuild, repair, and modular system assembly without excess inventory.

Each bolt in this kit features a 6-point socket head design—the industry standard for maximum engagement surface and torque transmission without stripping or cam-out risk. The 5/16-18 thread specification indicates a 5/16-inch diameter shaft with 18 threads per inch, optimized for medium-duty fastening in aluminum and steel applications. At 5.000 inches in length, these bolts accommodate assemblies requiring substantial grip range while maintaining clean geometry. ARP fasteners are manufactured to exacting tolerances and material standards, ensuring consistent clamping load and fatigue resistance across repeated assembly and disassembly cycles—critical for field-serviceable tactical systems.

This bolt kit is ideal for operators, armorers, and maintenance teams working with modular firearm platforms, optics mounting systems, rail assemblies, and equipment frames where precision fastening prevents zero shift and structural failure. The 6-point socket head design reduces torque loss and hand tool slippage—essential when working in field conditions or with gloved hands. Technicians should verify thread compatibility and apply appropriate locking compound per application requirements; the kit's compact 0.72-pound package fits easily in any tactical maintenance kit or gunsmith workbench setup.
