What it is

A Taptite thread-forming screw with an M4 thread, supplied by Biasi as part number BI1013111. It is a service fixing used on Biasi domestic gas boiler assemblies, where a thread-forming screw is driven into the component to hold covers, brackets and panels in place. It is listed for use across a broad range of Biasi boiler families.

Signs this part needs replacing

  • The fixing is missing from a cover, bracket or panel after a service or repair.
  • The thread is stripped or cross-threaded and the screw will not tighten.
  • The head is rounded or chewed, making the screw hard to drive or remove.
  • The screw is corroded or rusted.

Before you order

  • Confirm the thread size and length required against your appliance's parts list.
  • Check the model and GC number of the boiler you are working on.
  • Check whether the fixing point takes a thread-forming Taptite screw or a machine screw.
  • Confirm how many fixings you need.
