What it is

The Glow-worm 0020020740 is a flanged nut for use in Glow-worm gas boilers. It provides a secure threaded fixing where a flanged seating face is required. The part sits within the screws, nuts, bolts and clips category of gas boiler spares.

Signs this part needs replacing

  • Corrosion or rust visible on the nut body or flange
  • Rounded or damaged hex flats that prevent correct tightening
  • Stripped, cross-threaded or worn internal thread
  • The nut has worked loose or is missing from its fixing point
  • Leakage or weeping at the joint the nut secures

Before you order

  • Confirm the part number 0020020740 matches the entry on your appliance's parts list
  • Check your boiler model against the fitment list above
  • Compare the thread and flange dimensions with the nut being removed
  • Ensure the fixing point requires a flanged nut rather than a plain nut
