What it is

This is a Riello screw, spacer and bolt fastener supplied as part of the Riello burner spares range. It is used to secure and space components on Riello oil and gas burners fitted to boilers. The part carries the manufacturer reference 3003843.

Signs this part needs replacing

  • Corrosion or surface pitting on the screw, spacer or bolt
  • Rounded or damaged head that will not take the correct tool
  • Damaged or flattened threads that will not torque down cleanly
  • Fastener works loose in service, allowing the component it holds to move
  • Fastener missing after a burner strip-down or service

Before you order

  • Confirm the burner model and code against the Riello parts list for your appliance
  • Check the quantity of fasteners required for the job, as more than one may be used
