12pt SS Nut 5/16-24 2pk

The 12pt SS Nut 5/16-24 2pk delivers precision fastening for high-performance tactical and military applications where reliability under extreme conditions is non-negotiable. Engineered for systems requiring secure, vibration-resistant assembly, this two-pack offers the redundancy professionals demand when downtime or component failure cannot be tolerated. Whether you're building custom AR platforms, assembling precision competition rifles, or servicing duty weapons, these stainless steel fasteners provide the foundation for repeatable accuracy and dependable operation.

Manufactured from stainless steel, the 12pt SS Nut 5/16-24 features a twelve-point design that distributes load evenly across the fastening surface, reducing stress concentration and minimizing the risk of galling or stripping under heavy torque cycles. The 5/16-24 thread specification ensures compatibility with standard ARP fastener systems and precision component platforms commonly found in match-grade and tactical builds. Stainless construction resists corrosion, salt exposure, and environmental degradation—critical for weapons stored in vehicle safes, field conditions, or maritime environments where standard hardware would degrade within months.

Law enforcement armorers, precision rifle builders, and tactical equipment technicians rely on this fastener specification when assembling upper receiver components, scope mount systems, and precision mechanical assemblies where loose fasteners create unacceptable accuracy variance. The two-pack quantity supports complete builds or provides backup inventory for field maintenance. Pair with corresponding ARP bolts and apply proper torque specifications to lock-tight compound for optimal security in recoil-intensive applications.
