What it is

The Worcester Bosch 87133057650 is a set of nuts supplied as a service fastener for Worcester Bosch and British Gas badged gas appliances. The nuts clamp and secure components within the unit, holding joints tight under the vibration and repeated thermal cycling that a boiler experiences in normal use. Supplied as a set so that a joint can be rebuilt with matching fasteners rather than reusing worn originals.

Signs this part needs replacing

  • Visible corrosion or rust on the nut faces, common where a joint has been exposed to condensate or repeated heating cycles.
  • Rounded or chewed hex heads, which usually indicates the nut has been removed before and can no longer be torqued correctly.
  • Fasteners that have worked loose, allowing movement or a loss of clamping force at the joint.
  • Weeping, staining or crusting around a joint that was previously dry.
  • A service or repair where the existing nuts are being reused and no longer hold their torque.

Before you order

  • Confirm the appliance model and GC number against the compatibility list; the same set is used across a wide range of Worcester Bosch and British Gas badged boilers.
  • The alternative part number 1012769 identifies the same set of nuts, so either number can be used to cross-reference stock.
  • Have the appliance GC number and serial number to hand when checking the parts list for the joint you are working on.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
