What it is

This is an M4 x 6mm screw from Main, listed within the manufacturer's water heater spares range. It is a small threaded fastener used to secure components on Main Multipoint water heaters. It is supplied as a single screw.

Signs this part needs replacing

  • The screw head is rounded or chewed, so a driver no longer grips it
  • The threads are stripped or the screw will not tighten
  • Corrosion or rust is visible on the screw body or head
  • The screw is missing and the component it secures is loose or rattling
  • The screw has seized in place and cannot be removed without damage

Before you order

  • Confirm your appliance model against the fitment list above
  • Check the thread size and length required against the screw being replaced
  • Check how many screws are needed for the job, as this listing is for one screw
  • Inspect the mating thread or fixing point for damage before fitting
