S/S Bolt Kit - 12pt. (5) 1/4-20 x 2.750

The S/S Bolt Kit - 12pt. (5) 1/4-20 x 2.750 is a premium fastener solution engineered for high-performance tactical applications where reliability and precision are non-negotiable. Whether you're assembling upper receivers, securing optic mounts, or performing critical maintenance on precision rifle platforms, this ARP stainless steel bolt kit delivers the corrosion resistance and dimensional accuracy that operators and gunsmiths depend on in the field. Five bolts per kit ensure you have backup fasteners for redundancy—a practice standard in professional shooting and law enforcement armory operations.

Manufactured from 300M stainless steel by ARP, these 1/4-20 fasteners feature 12-point head geometry that provides superior wrench engagement compared to standard 6-point designs, reducing the risk of bolt head stripping during assembly and disassembly cycles common in tactical environments. The 2.750-inch length accommodates most upper receiver assemblies and accessory mounting applications without requiring washers or adapters. Stainless construction resists saltwater corrosion, humidity, and rapid temperature cycling—critical in deployments ranging from humid coastal regions to arid high-altitude operations where carbon steel bolts degrade rapidly.

This bolt kit is ideal for AR platform builders, precision rifle gunsmiths, and maintenance-focused operators who prioritize consistency and durability over cost-cutting fasteners. The 1/4-20 thread pitch is standard across most upper receiver platforms and optic mounting systems, making this kit a universal choice for equipment upgrades and repairs. Keep a kit on hand in your armory or field kit—stainless fasteners are easier to identify during low-light maintenance, and the 12-point head design significantly speeds assembly when wearing heavy gloves or operating under time constraints.
