The S/S Bolt Kit - 12pt. (5) 1/4-20 x 3.250 is a precision stainless steel fastener set engineered for tactical platforms, firearms assemblies, and mission-critical equipment where corrosion resistance and structural integrity are non-negotiable. Purpose-built for law enforcement, military, and serious civilian operators, this five-piece bolt kit delivers the reliability demanded in high-stress environments where component failure is not an option. Whether securing optic mounts, rail systems, chassis components, or lower receiver assemblies, this fastener kit provides the dependable anchor point your tactical build requires.
Manufactured from stainless steel and finished with a 12-point socket head design, the S/S Bolt Kit - 12pt. (5) 1/4-20 x 3.250 offers superior corrosion resistance compared to standard zinc-plated fasteners, making it ideal for field use in moisture-prone environments. The 1/4-20 thread specification (1/4-inch diameter, 20 threads per inch) is a standard across tactical accessories and aftermarket firearm components, ensuring broad compatibility. At 3.250 inches in length, these bolts accommodate thicker material stacks and provide adequate standoff for properly spaced mounting applications without protruding or binding internal components.
Operators and gunsmiths rely on quality stainless fasteners for scope base installation, handguard attachment, quick-detach (QD) socket mounting, and precision rifle builds where dimensional consistency matters. The five-bolt quantity is sufficient for a complete optic mounting pair or serves as a replacement and spare set for ongoing maintenance cycles. Installation is straightforward with standard 3/8-inch hex key or socket tool compatibility; torque to manufacturer specifications for your specific firearm platform to ensure zero retention and safe operation in the field.
