What it is

The Alpha self tapping screw measures M4.2 x 19 mm and is supplied under part number 1.019640. It is used across the Alpha CD and Commercial PRO TEC appliance families. The self-tapping thread cuts its own path into the mounting material, securing panels and components during service and repair.

Signs this part needs replacing

  • The screw head is rounded or stripped, preventing a driver from turning it.
  • The thread is damaged, cross-threaded or no longer grips the mounting point.
  • Corrosion or rust is visible on the screw body or head.
  • The screw is missing or has been lost during a previous repair.

Before you order

  • Confirm the screw dimensions are M4.2 x 19 mm.
  • Check your appliance model against the fit list above.
  • Confirm the fixing point requires a self-tapping screw.
