What it is

The Worcester Bosch 87161401020 is an M4 extended nut supplied as fixing hardware for Worcester gas boilers. It sits within the manufacturer's screws, nuts, bolts and clips range and is used on the appliance families listed below.

Signs this part needs replacing

  • Threads are stripped, cross-threaded or will not tighten correctly
  • The nut is seized on its stud or bolt and cannot be removed without damage
  • Corrosion or rounded hex flats prevent a spanner or socket from gripping
  • The nut is missing or has been lost during servicing
  • A joint it secures has worked loose, allowing component movement

Before you order

  • Confirm the part number 87161401020 matches the entry in your appliance's parts list
  • Check that an M4 extended nut is the correct fixing for the joint, rather than a standard M4 nut
  • Confirm how many nuts are required for the repair
  • Have the appliance model and GC number to hand when checking compatibility
