BS EN 4011 is a European Standard that discusses components and fasteners used in aerospace applications.
BS EN 4011 is a European Standard that specifies the characteristics of self-locking bihexagonal nuts in NI-PH2601, silver-plated, for aerospace applications. The classification is 1 550 MPa / 600 °C.
BS EN 4011 on bihexagonal self-locking nuts for aerospace applications is useful for:
When it comes to the manufacturing and use of aerospace components, reliability, consistent performance and durability are crucial.
BS EN 4011 provides best industry guidance on the appropriate dimensions, tolerance and mass while recommending reference standards for materials and surface treatments to be considered for bihexagonal self-locking nuts used in the aerospace industry. With the right materials and surface treatments, you can ensure that the nuts do not in any way impair the performance or efficiency of the end-application.
If you are a manufacturer of bihexagonal self-locking nuts used in the aerospace industry, compliance with these requirements can ensure your products meet the performance needs of the end-application.
BS EN 4011 creates a standardized approach for manufacturers of bihexagonal self-locking nuts to adhere to if they supply their components for use by the aerospace and defence industry.
With compliance to BS EN 4011 you can demonstrate the reliability of bihexagonal self-locking nuts and build trust in their use throughout the aerospace supply chain.
