Pneumatic box-end wrench D 3550 series

Our flat head wrenches are preferably used for screw-assembly in space-limited areas. The flat head wrenches are available with interchangeable socket inserts – also customer specific. For tube- and pipe assemblies, we recommend the use of flat head wrenches with an open head. The different head-length (L) allows the adaptation of the driver to many different access locations. If the supply-air is shut-off, then the tool can be used to retighten a connection. Typical applications for flat head wrenches are any hose- and pipe-assemblies requiring connector nuts, such as is the case in the automotive assembly.
