RS PRO Bright Zinc Steel Locknut Nylon Insert Size M20 Width 19mm Overall Height 22mm DIN 982 276-796

RS PRO 276-796 Bright Zinc Steel Locknut features a nylon insert designed to provide safe and secure fastening in conditions of severe vibration. Manufactured from grade 8 steel with a bright zinc plating, this locknut offers long-lasting durability and environmental resistance. The nylon insert deforms to the thread of the fastener, preventing loosening without additional locking adhesives, making it ideal for high-vibration environments.

This locknut meets DIN 982 standards, ensuring industry compatibility and quality assurance. Its size M20, with a 19mm width and 22mm overall height, makes it suitable for various heavy-duty applications where a secure fastening is critical.

The locknut is commonly used in industrial machinery, automotive manufacturing, and domestic appliances such as washers and dryers, where vibration and dynamic loads require reliable fastening solutions.

Unlike conventional nuts, the nylon insert improves locking effectiveness, especially when joining soft materials such as wood and plastics, protecting the material from damage. It is recommended to finger tighten first and then torque with an appropriate tool to reach specified tension.

While these locknuts can be removed and reused, it is advisable to avoid reusing them when possible, as the nylon insert's effectiveness diminishes after each use. Constructed from grade 8 steel for high strength and durability.

Features glass-filled nylon insert to resist loosening under vibration. Bright zinc plating ensures corrosion resistance and long service life. Conforms to DIN 982 standard for lock nuts. Metric size M20 with width 19mm and height 22mm.
