BS EN 3709 is a European standard on aerospace series which covers wrenches and sockets, bi-hexagonal. Technical specification,
BS EN 3709 specifies the requirements to be complied with by wrenches and double-hex sockets intended for aerospace products.
BS EN 3709 on wrenches and sockets is useful for:
A socket wrench is a type of spanner, that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 3709 walks you through the requirements to be complied with by wrenches and double-hex sockets intended for aerospace products. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
