What it is

This is a Worcester Bosch M5 x 10mm taptite screw supplied in a pack of ten. It is a zinc-plated Phillips-drive fixing used to secure panels, brackets and internal components on Worcester Bosch gas boilers, and it appears across a wide spread of the manufacturer's older and current appliance families. Taptite thread-forming screws of this type are used where a fixing needs to bite into a formed or punched hole and hold firm against boiler vibration.

Signs this part needs replacing

  • A fixing has worked loose and the panel, bracket or component it holds is no longer secure
  • The screw head is rounded or chewed, so the correct driver no longer grips it
  • Visible corrosion or white zinc breakdown on the screw, common where a boiler has been damp or leaking
  • Threads have stripped out of the hole after repeated removal and refitting during servicing
  • A screw is missing altogether after a previous repair, leaving an unfastened cover or mounting point

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the correct fixing for your model
  • Confirm the quantity needed against the pack of ten, particularly where several fixings are being replaced at once
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
