U-Nut (DIN980M) is an all-metal self-locking nut designed to help prevent loosening caused by vibration, movement, and dynamic load. It is commonly used in machinery, automotive, construction, equipment assembly, metal fabrication, repair work, and general industrial maintenance applications where secure fastening and anti-loosening performance are required.

DIN980M is a prevailing torque type all-metal lock nut. Unlike nylon insert lock nuts, it does not rely on a nylon ring to create locking resistance. Instead, the locking action is created by metal-to-metal friction and the internal locking design of the nut. This makes it suitable for applications where an all-metal locking nut is preferred.

U-Nut (DIN980M) is a practical option for users who need vibration-resistant fastening in mechanical assemblies, moving equipment, structural components, and industrial applications. It should be used with compatible bolts, screws, studs, or threaded rods of the correct size and thread pitch.

Why Choose Our U-Nut (DIN980M)

Choosing the correct lock nut material, thread size, and finishing is important for fastening safety, vibration resistance, corrosion protection, and long-term performance. U-Nut (DIN980M) is suitable for users who need an all-metal self-locking nut for bolts, screws, studs, and threaded rods.

Steel U-Nut (DIN980M) with Zinc Plated Finishing is a practical and cost-effective choice for general machinery, automotive, construction, fabrication, repair, and maintenance applications. Stainless Steel 304 (A2) is suitable for applications requiring better corrosion resistance, especially in cleaner, semi-outdoor, or moisture-prone environments.

The all-metal prevailing torque design helps improve locking performance by adding resistance against loosening, making it suitable for assemblies exposed to vibration, movement, heat, or repeated operation. We supply U-Nut (DIN980M) for contractors, factories, machinery service teams, automotive workshops, maintenance departments, metal fabricators, engineering companies, and industrial customers in Selangor, Kuala Lumpur and across Malaysia, including Klang, Shah Alam, Puchong, Petaling Jaya, Subang, Port Klang, Balakong, Cheras, Kajang, Rawang, Semenyih, Ampang, Banting, Putrajaya, Cyberjaya and Seremban.
