What it is

The Schwank 23002256 is a hexagonal nut made to the DIN 934 / ISO 4032 standard, in M4 thread size and 1.4301 stainless steel. It is a fastening component used on Schwank heating appliance assemblies where a metric M4 threaded fixing is required. The hexagon form allows the nut to be run up with a standard spanner or socket.

Before you order

  • Confirm the fixing point uses an M4 thread and that the DIN 934 / ISO 4032 hexagon form is the correct pattern for the assembly.
  • Check that 1.4301 stainless steel is suitable for the location, particularly where the nut sits on flue, combustion or condensate-affected components.
  • Work out how many nuts the job needs, since these are supplied as individual fixings rather than in a stated pack quantity.
