What it is

The Alpha 1.4066 is a self tapping screw measuring 3.5 mm x 9.5 mm, listed by Alpha for use across its gas boiler range. It is a fixing screw used to secure panels, brackets and internal components within the appliance. It sits in the screws, nuts, bolts and clips category of the Alpha boiler spares range.

Signs this part needs replacing

  • The cross head is rounded or stripped, so the screw can no longer be driven or removed cleanly.
  • The threads are corroded, rusted or flattened and no longer bite into the fixing point.
  • The screw is seized or cross-threaded in its hole.
  • A screw is missing, leaving a panel, bracket or cover insecure.
  • The screw spins in place without tightening.

Before you order

  • Confirm the screw dimensions (3.5 mm x 9.5 mm) match the one removed from the appliance.
  • Check the boiler model and GC number against the fitment list above.
  • Count how many screws are required for the job before ordering.
  • Inspect the fixing point for damaged or stripped threads that may need attention.
