What it is

The Main M4 x 20mm stud is a threaded fastener used on Main gas boilers, including the Combi ECO, ECO Elite and System ECO ranges. It secures components within the appliance assembly where a fixed threaded stud is required rather than a bolt. It is supplied under Main part number 5130600.

Signs this part needs replacing

  • Threads are stripped, cross-threaded or will not hold torque
  • Visible corrosion or pitting on the stud body or thread
  • The stud has sheared or snapped during servicing
  • The component it secures has worked loose or is rattling
  • The stud spins in its mounting point instead of gripping

Before you order

  • Confirm your appliance model against the fit list above
  • Check the thread size and length required against the stud being replaced
  • On ErP Combi and System models, check the serial number prefix where the fit list distinguishes between them
  • Confirm how many studs are needed for the repair
