What it is

The Hamworthy H.S.I and flame probe retaining screw is an M3 x 8mm socket cap head screw for securing the H.S.I and flame probe assembly in Hamworthy gas boilers. It is listed in the Gas Boiler Spares range under part number 748013353.

Signs this part needs replacing

  • The retaining screw is missing, loose or has backed out
  • The screw thread is stripped, so it will not hold tightly
  • The screw head is damaged, making it hard to tighten or remove
  • The H.S.I or flame probe sits loose or out of position
  • Ignition or flame sensing faults where the probe has shifted

Before you order

  • Check your boiler model against the fits list above before ordering.
  • Confirm the existing screw is M3 with an 8mm length and a socket cap head.
  • Inspect the old screw and its threaded hole for damage that could affect the new screw.
