What it is

The Worcester Bosch M6 nut, part number 8738903410, is a threaded fastener sold in a pack of 10. It is used in Worcester Bosch Greenstar boilers to secure internal components. It is listed for the Greenstar 1000 Series and Greenstar models below.

Signs this part needs replacing

  • The nut's thread is stripped, cross-threaded or worn, so it will not tighten securely.
  • The nut is corroded or seized and cannot be removed without damaging the thread.
  • A nut is missing or loose on a component it should secure.
  • The nut or its bolt shows visible damage, cracking or deformation.

Before you order

  • Confirm the appliance is a Worcester Greenstar 1000 Series or Greenstar model listed above, and that the model and gas type match your boiler.
  • Check that the fastener is M6 thread and that the bolt or stud it fits onto is also M6.
  • Note that this product is sold as a pack of 10, so confirm the quantity you need before ordering.
