What it is

A Torx-head screw measuring 4.2mm x 13.5mm, manufactured by Glow-worm and supplied under part number 0020020773. It is a fixing component used on Glow-worm Flexicom gas boilers, where it secures internal panels and assemblies during servicing and repair. It sits within the screws, nuts, bolts and clips category of boiler spares.

Signs this part needs replacing

  • The Torx head is rounded or chewed, so the driver no longer grips
  • Visible corrosion or rust on the screw shank or head
  • Threads are stripped or cross-threaded in the fixing point
  • The screw is missing, leaving a panel or assembly insecure
  • The screw has been over-tightened and stretched or snapped

Before you order

  • Check the existing screw dimensions and head type match 4.2mm x 13.5mm Torx
