What it is

The Worcester Bosch 29144114240 is an M4 x 6 Taptite screw used to secure internal components inside Worcester Bosch gas appliances. It is listed by the manufacturer as a Zebra Pias screw within the screws and studs spare part range. Taptite thread-forming screws of this type hold assemblies firmly against vibration and thermal movement, so they are commonly found on burner, casing and internal bracket fixings.

Signs this part needs replacing

  • A fixing that will not tighten, indicating stripped or crossed threads
  • Corrosion or surface pitting on the screw head or shank
  • A screw that has worked loose and is allowing a component or casing panel to move
  • Visible thread damage after removal during servicing
  • A missing fixing where a component is no longer held securely

Before you order

  • Check the appliance GC number and model against the compatibility list, as this screw is shared across a wide range of Worcester Bosch units.
  • Confirm the existing fixing matches the M4 x 6 Taptite specification before ordering.
  • Note the alternative part number 1011155 when cross-referencing older documentation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
