NFE 25511 Lock Washer

The knurled surface of the NFE 25511 Lock Washer by Dazhe manufacturer greatly enhances its anti-slip and anti-loosening capabilities, effectively preventing thread loosening in a vibrating environment and ensuring the stability of the connection.

Our NFE25511 Lock washer, also known as French-type locking washers, are single-sided embossed disc lock washers compliant with French standards.

Available in spring steel, stainless steel 304/316 grades, the French-type single-tooth anti-loosening washers supplied by Dazhe feature excellent elasticity. They can effectively compensate for the settlement deformation of assembled materials and minimize pressure loss. When compressed flat during installation, these washers ensure uniform stress distribution on the tightened components. Moreover, they are among the special-purpose locking washers for railway locomotives.

Product Features

The unique single-sided embossed disc structure of the French lock pad enables the overall shape to meet the requirements of the installation scenarios, and is suitable for various connection and assembly scenarios of general machinery. The concave-convex surface design enhances the contact and interlocking effect with the connecting parts, ensuring a stable connection even under continuous vibration conditions, and preventing the occurrence of screw loosening problems.

It is made of high-quality materials such as spring steel and 304, 316 stainless steel, featuring excellent elasticity. It can flexibly adapt to the displacement and deformation of the materials during assembly, reducing pressure loss. In the compressed flattened state, it can achieve uniform stress distribution, reducing the risk of excessive local stress on the fastening components and prolonging the service life of the connection parts.

Not only is it suitable for the load-bearing and non-load-bearing structures of general machinery, but it can also meet the usage requirements of special scenarios such as railway locomotives. The application range is extensive. The combination of material properties and structural design enables the product to maintain stable performance even under frequent disassembly and assembly scenarios, eliminating the need for frequent replacements and improving the efficiency of assembly and maintenance.
