Fuel injection valve for combustion engines

The valve (100) has a nozzle body (11) indirectly axially braced in a housing (10) against a support body (15) by a clamping nut (18). A threaded connection (20) is formed between the support body and the clamping nut in a region axially spaced to the nozzle body. The threaded connection comprises toothed regions (21, 22) with different screw thread dimensions, which are axially arranged one behind the other along longitudinal direction of the housing. A screw thread-free intermediate region (23) is formed between the toothed regions.
