Product Description The Hillman 5/16"-18 Coarse Thread Nylon Hex Nuts provide a reliable fastening solution for a wide range of electrical and mechanical applications. These durable nylon hex nuts are designed to be used with compatible machine bolts, machine screws, or threaded rods, helping secure materials while preventing tension and shear movement in assembled components. Manufactured from high-quality corrosion-resistant nylon, these plastic hex nuts will not rust or corrode like traditional metal fasteners, making them ideal for environments where moisture or chemical exposure may occur. The lightweight and non-conductive nylon fastener design also makes them particularly suitable for electrical hardware installations, appliances, electronics, and mechanical assemblies. Each nut features a 5/16"-18 USS coarse thread, ensuring proper compatibility with standard 5/16-18 bolts, threaded rods, and machine screws. The precision molded threads provide secure fastening while maintaining durability during installation. These coarse thread nylon nuts are part of Hillman’s complete fastening solution and are recommended for general hardware repairs, electrical components, mechanical equipment, DIY home improvement projects, and maintenance work. For best installation results, pair these 5/16-18 hex nuts with bolts or machine screws of the same thread size and avoid overtightening to prevent stripping the nylon threads. From the Manufacturer Hex nuts are for general applications and are used with bolts and washers of the same finish. The most commonly used nut, they are often found in deck and fence building. The called out size is the inner diameter and the number of threads per inch or thread pitch.
