5/16-24 RH Steel Jam Nuts 10pk

The ALLSTAR PERFORMANCE 5/16-24 Right-Hand Steel Jam Nuts 10-pack (SKU ALL18252-10) provides precision fastening for motorsports applications, machine assembly, and mechanical systems where vibration isolation and load security are critical. These zinc oxide-coated steel jam nuts are engineered to lock standard fasteners in place, preventing unintended loosening during high-vibration operation—a proven standard in racing, engine builds, and industrial assembly.

The 5/16-24 metric specification indicates a 5/16-inch diameter with 24 threads per inch, right-hand thread orientation for standard clockwise tightening. Jam nuts function by creating a locking force when two nuts are threaded onto a single fastener—the upper nut is tightened first, then the jam nut is turned against it, trapping the bolt and preventing rotation under load. Steel construction with zinc oxide plating delivers corrosion resistance suitable for engine compartments and outdoor mechanical environments. The compact 10-pack configuration suits both maintenance tasks and small production runs.

Buyers working on engine rebuilds, carburetor tuning, fuel system assembly, and suspension geometry commonly stock jam nuts in multiple metric sizes to ensure proper fastener security across diverse component applications. ALLSTAR PERFORMANCE manufactures components specifically for racing and high-performance automotive use, where bolt security under extreme acceleration and vibration is non-negotiable.

This 10-pack provides immediate inventory for technicians and builders who require redundant fastening methods on critical assemblies, offering cost-effective assurance that precision-threaded connections remain locked throughout service cycles.
