What it is

The Worcester Bosch 8737709304 is a fixing set made up of an M6 nut and an M6 x 30mm screw with a property class of 5.8. It is a Worcester Bosch component intended for use on Greenstar appliances, where the threaded pair holds internal components and assemblies together. The screw length and thread size make it a direct replacement for the original fixing on the appliances listed below.

Signs this part needs replacing

  • Corrosion or surface rust on the nut or screw shank, making the thread difficult to turn
  • A rounded or chewed hex head caused by a slipping spanner or socket
  • The fixing works loose under vibration and will not hold torque
  • The nut or screw is missing after a previous strip-down, leaving a component unsecured
  • Visible thread damage or cross-threading that prevents the fixing seating correctly

Before you order

  • Check the appliance GC number or serial plate against the compatibility list to confirm the fixing is correct for your model
  • Match the part number 8737709304 and the alternative number 2249230 against the fixing being replaced
  • Confirm the thread size and screw length required, as other M6 fixings of a different length are used elsewhere on these appliances
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
