The Jam Nut Steel RH 10/32 is a precision fastening component engineered for marine equipment, engine rebuilds, and critical assembly work where vibration resistance is non-negotiable. Built by KING RACING PRODUCTS, this right-hand threaded jam nut secures components on 10-32 threaded studs and bolts—a standard size found across outboard motors, fuel systems, water intakes, and mechanical assemblies on recreational and commercial vessels. Boaters and marine technicians rely on jam nuts to lock primary nuts in place, preventing unwanted loosening from engine vibration, wave action, and thermal cycling.
Manufactured from hardened steel with a zinc oxide protective finish, the Jam Nut Steel RH 10/32 resists corrosion in saltwater and freshwater environments while maintaining reliable clamping force over extended service intervals. The zinc oxide coating provides superior rust resistance compared to bare steel, a critical advantage for below-waterline fittings and engine compartments exposed to moisture. Its compact profile—measuring 1.55 inches in outer diameter with a minimal 0.3-inch thickness—allows installation in confined spaces typical of marine engine blocks and fuel delivery systems. The right-hand thread design conforms to standard fastener conventions, ensuring compatibility with all conventional 10-32 studs and bolts used in marine applications.
Marine technicians, engine builders, and experienced boaters benefit from stocking Jam Nut Steel RH 10/32 units for preventive maintenance and emergency repairs. This fastener excels in high-vibration environments where a primary nut alone cannot guarantee secure assembly—typical applications include carburetor linkages, thermostat housings, water pump fittings, and distributor cap mounting. Installation is straightforward: thread the jam nut onto the stud after the primary nut is set, then tighten firmly against the primary nut to create a locking pair that resists vibration-induced loosening. Each individually packaged unit weighs 0.01 pounds, making it ideal for tool kits, repair lockers, and emergency spares aboard vessel or in the shop.
