Why should you use BS EN 4108 - Crow foot wrenches?
A crowfoot wrench has a unique shape, this wrench was used in steam train repair work and to reach and to hold nuts and boltheads in difficult-to-reach places. Crowfoot wrenches are open-end sockets that come in handy when reaching around obstacles. They work where common 6pt and 12pt sockets and wrenches simply cannot fit.
Spline lug nuts are designed to fit in small diameter recesses found on aftermarket wheels. These lug nuts are characterized by their smooth exterior finish and internal splines on the top of the lug that's requires a spline drive adapter for installation and removal.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 4108 walks you through characteristics of crow foot wrenches for splined nuts. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
