What it is

This is a Worcester Bosch M6 x 18mm screw, supplied in a pack of 10 and listed under part number 8737602143. It is a fixing screw for Worcester Greenstar boilers, and the fit list below shows the models it is recorded against.

Signs this part needs replacing

  • A screw is missing from a boiler casing panel or front cover, so the panel is loose or not held square.
  • The screw head is stripped or rounded, and a driver cannot grip it to tighten or remove it.
  • The thread is damaged, cross-threaded or worn, so the screw will not hold its fixing position.
  • The screw has corroded or snapped, leaving a fixing point that can no longer be secured.

Before you order

  • Check your boiler model and LPG or NG variant against the fit list above.
  • Confirm the removed screw is M6 x 18mm before ordering, particularly if the thread or head type looks different.
  • Note that this listing is a pack of 10, so check how many you need for the job.
