What it is
This is a Worcester Bosch Taptite screw measuring M4 x 8 mm, supplied with a pan head and a zinc plated finish. Taptite thread form is designed to cut its own mating thread as it is driven, which makes it a common fixing for brackets, panels and internal assemblies inside Worcester Bosch gas appliances. It is a small but load-bearing fixing, and a worn or corroded screw can allow the component it holds to work loose.
Signs this part needs replacing
- Corrosion or breakdown of the zinc plating on the head or along the thread
- A rounded or chewed head that no longer accepts a driver cleanly
- Stripped or flattened thread that will not grip the parent material
- The fixing works loose under vibration, leaving a bracket, panel or cover rattling
- The screw has seized in place after repeated heat cycling and will not release
Before you order
- Check the GC number on the appliance data badge against the compatibility list before ordering, as this fixing is shared across a large number of Worcester Bosch models.
- Confirm the part number 29144114120 or the alternative number 1011151 matches the fixing being replaced.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
