1/4-28 RH Steel Jam Nuts 50pk

The 1/4-28 RH Steel Jam Nuts 50pk from ALLSTAR PERFORMANCE delivers a reliable fastening solution for precision mechanical assemblies where thread-locking and vibration resistance are critical. Jam nuts serve as secondary locking elements, preventing fastener loosening under repeated vibration, shock loads, and thermal cycling—making them indispensable in automotive, motorsports, and industrial applications. This 50-pack format ensures you maintain adequate inventory for repairs, maintenance, and new builds without frequent reordering.

Engineered from steel with a zinc oxide finish, these right-hand thread jam nuts provide corrosion resistance and durability in demanding environments. The 1/4-28 thread pitch specification indicates a 1/4-inch diameter with 28 threads per inch—a metric common in fine-thread applications where precision clamping force and reduced vibration transmission are required. Installation involves threading the jam nut flush against a primary fastener; the resulting friction and mechanical interference between the two nuts creates a self-locking effect without adhesive dependency. Steel construction ensures tensile strength and thermal stability across temperature ranges typical in engine bays, suspension systems, and transmission assemblies.

Professionals in performance automotive, racing, and machinery maintenance rely on jam nuts for applications where standard fasteners alone cannot guarantee secure, long-term retention. The 50-piece count supports both production runs and field repairs, reducing downtime from fastener failure. Right-hand thread orientation matches standard U.S. fastener conventions, ensuring compatibility with conventional bolts, studs, and threaded rod across engine components, brake systems, fuel system fittings, and structural fastening points.
