Bolt Kit - SS 12pt 5pk 10mm x 1.25 x 30mm

The Bolt Kit - SS 12pt 5pk 10mm x 1.25 x 30mm by ARP is a precision fastener solution engineered for demanding tactical and military applications where reliability under extreme conditions is non-negotiable. This five-piece stainless steel bolt kit addresses the core requirement facing operators and armorers: securing critical components with hardware that resists corrosion, maintains structural integrity under sustained use, and performs consistently across deployment environments. Whether you're building a custom rifle, maintaining department inventory, or servicing equipment in salt-laden or high-humidity operational theaters, quality fasteners form the foundation of weapon system dependability.

Each bolt in this kit features a 12-point head design, which distributes load more evenly than traditional six-point fasteners and reduces the likelihood of cam-out during installation—a critical advantage when working in field conditions or with limited tool access. The 10mm x 1.25 x 30mm specification (metric thread pitch of 1.25mm, 30mm shank length) delivers optimal clamping force for precision-toleranced tactical components without over-tightening that can strip threads or compromise fit. Constructed from stainless steel (typically 18-8 or 316-grade), these bolts resist rust and corrosion far superior to zinc-plated alternatives, making them ideal for wet environments, coastal deployments, or long-term storage without maintenance. The compact 0.37 lb weight and compact dimensions ensure minimal impact on overall system balance or packaging constraints.

Law enforcement armorers, military technicians, and serious civilian builders rely on metric fastener kits like this for upper and lower receiver assembly, optic mount systems, rail attachment, and chassis component installation. The five-pack quantity is ideal for individual rifle builds or small-batch maintenance cycles, eliminating the waste of oversized boxes while ensuring spares for field replacement. Compatibility spans all standard AR-platform variants, precision rifle builds, and any tactical system calling for M10 x 1.25 fasteners; verify thread pitch and shank length against your specific application before installation to ensure proper fit and safety. Store bolts in a dry environment and apply a light anti-seize compound to threads if operating in extreme salt or chemical environments.
