What it is

The Worcester Bosch 29110811180 is a brass hex head screw with an M4 x 8mm thread. It is a fixing component used in Worcester Bosch gas boiler assemblies. The screw is listed for applications across the 24I, 28I and 35 CDI appliance families.

Signs this part needs replacing

  • The hex head is rounded or chewed, so a socket or spanner will not grip it.
  • Visible corrosion, pitting or green discolouration on the brass surface.
  • Threads are stripped, cross-threaded or otherwise damaged.
  • The screw is missing from its fixing point, leaving the component it secures loose.
  • The screw turns freely and will not hold torque.

Before you order

  • Confirm your boiler model against the fit list above.
  • Check the thread size and length of the screw being removed — M4 x 8mm is not interchangeable with other sizes.
  • Inspect the mating thread in the boiler component for damage before fitting a new screw.
  • Check how many screws are needed to complete the repair.
