9mm x 1.00 12pt. Nuts (10)

The ARP 9mm x 1.00 12pt. Nuts (10) are precision fasteners engineered for demanding tactical, military, and law enforcement applications where reliability under stress is non-negotiable. Built from chromoly steel and finished in black oxide, this 10-piece set delivers the durability required in high-performance firearm builds, AR platform assembly, and critical equipment maintenance. Whether you're a gunsmith, armorer, or tactical professional, these fasteners provide the strength and corrosion resistance necessary for field-proven performance.

Manufactured from chromoly steel, the 9mm x 1.00 12pt. Nuts feature a metric 9mm bore with 1.00mm thread pitch and a 12-point head design that distributes load evenly across fastening surfaces—critical for preventing fastener rotation and stress concentration in reciprocating or vibration-prone applications. The black oxide finish provides robust corrosion protection while maintaining a low-reflectivity profile essential in tactical environments. The 12-point head geometry also enables wrench engagement from multiple angles, improving accessibility in tight assembly spaces typical of modern firearm platforms.

Armorer and gunsmith professionals will recognize the critical role precision fasteners play in upper receiver assemblies, gas tube attachments, and rail system installation. This 10-piece set is ideal for complete AR builds, maintenance kits, or field repairs where metric fasteners must meet military-grade specifications. The chromoly construction resists shear and vibration loosening, making it essential for semi-automatic and automatic firearm platforms operating under sustained recoil stress. Stock a set in your armorer's toolkit for immediate availability during builds or emergency maintenance.
