What it is

The Worcester Bosch 87133011800 is an M8 flanged nut used on Greenstar gas boilers. The flanged base spreads clamping load across the mating surface, making it suitable for fixings where an M8 flanged nut is specified. It is a service part for the Worcester Bosch Greenstar range.

Signs this part needs replacing

  • Corrosion or rust on the nut or flange face
  • Rounded or damaged hex flats
  • Cross-threaded or stripped threads
  • The nut will not hold torque and works loose
  • Visible weeping or signs of escape at the joint it secures

Before you order

  • Check that the fixing point requires an M8 flanged nut.
  • Confirm how many nuts are needed for the job.
  • Work on gas-carrying components must be carried out by a Gas Safe registered engineer.
