Shank nuts are used majorly in aircraft engine applications. They are installed by flaring the nut shank with a conical tool.
BS EN 3014 specifies the characteristics of self-locking serrated shank nuts, for aerospace applications. Classification: 1 100 MPa 1) / 650 °C 2).
BS EN 3014 on characteristics of shank nuts is useful for:
Shank nuts are high temperature, high tensile strength nuts that are also are self-locking, self-retaining and self-wrenching. They come in a variety of configurations and materials.
BS EN 3014 includes configuration, dimensions, tolerances, masses, materials, thread, pitch diameter, designation and installation of shank nuts.
The guidelines in BS EN 3014 provide you with the standardized characteristics of shank nuts for industrial use so that the end customer gets a superior quality product.
