What it is

The Alpha 1.022320 is a self-tapping screw with an M3.5 thread and a 12 mm length, used on Alpha CD and HE gas boiler models. It cuts its own thread as it is driven in, so it can be fitted into casing and internal fixing points without a pre-tapped hole. It is a serviceable fixing for panels and internal assemblies.

Signs this part needs replacing

  • The screw head is rounded or chewed and the driver no longer grips it
  • The thread is stripped and the screw will not tighten
  • Corrosion or rust is visible on the screw body
  • The screw is missing after a service or panel removal
  • The panel or component it secures is loose or rattling

Before you order

  • Confirm the thread size and length needed at the fixing point
  • Check your appliance model against the fitment list
  • Check whether the screw secures a casing panel or an internal component, as length matters
  • Confirm the quantity required before ordering
