5/16 - 24 12pt Nut 1pk

The 5/16 - 24 12pt Nut 1pk from OPTITORQUE TECHNOLOGIES LLC is a precision fastener engineered for applications requiring secure, repeatable connections in mechanical assemblies. Manufactured from hardened steel with a black oxide finish, this single-pack nut is designed for technicians, maintenance professionals, and equipment builders who demand reliability in critical fastening tasks. The 12-point head geometry provides superior grip and reduced fastener rounding, making it ideal for both hand tools and pneumatic or electric wrenches across industrial, automotive, and tactical equipment platforms.

This nut features a 5/16-inch nominal diameter with a 24 threads-per-inch (TPI) pitch, delivering fine-thread engagement for applications where vibration resistance and load retention are paramount. The 12-point head design increases contact area compared to standard 6-point geometry, reducing stress concentration and minimizing fastener galling during installation and removal cycles. Black oxide plating provides corrosion protection in humid or outdoor environments while maintaining a professional appearance, and the hardened steel construction ensures consistent performance under mechanical stress without thread stripping or deformation.

Professionals working on precision machinery, firearm accessories, optical mounts, and structural assemblies benefit most from the fine-pitch specification and multi-point design of this fastener. The 5/16-24 thread pitch suits applications where standard coarse threading (5/16-18) would be inadequate, offering tighter tolerances and reduced backlash in critical adjustment mechanisms. Installation is straightforward with any standard wrench or socket; the 12-point head accommodates multiple approach angles, simplifying work in confined spaces and reducing installation time.
