BS EN 4111 is a European standard on aerospace series which covers wrenches, splined, sockets, for pipe fittings. Technical specification.
BS EN 4111 specifies the requirements which must be met by hand-operated splined wrenches and sockets for aerospace applications.
BS EN 4111 on splined wrenches and sockets is useful for:
Splined wrenches are designed to service high tensile strength fasteners used widely on military and commercial aircraft and in heavy machinery applications where vibration is prevalent. They are also used in automotive and industrial areas where high performance torque needs to be achieved.
A spline socket is designed to tighten and un-tighten spline fasteners but is also ideal for use on 4-point, 6-point (hex) and 12-point (bi-hex) fasteners, making them a useful socket to use across multiple shaped fasteners.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 4111 walks you through the requirements which must be met by hand-operated splined wrenches and sockets. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
