What it is
The Worcester Bosch 87186819060 is a G1/2 nut used to secure threaded connections inside Worcester Bosch heating appliances. It forms part of the nuts and bolts fixing range and is used where a joint needs to be drawn down and held under load. Correctly torqued, it keeps the connection tight so the appliance continues to run reliably.
Signs this part needs replacing
- Visible corrosion, rust or pitting on the nut body or threads
- Rounded or chewed flats caused by a previous removal with the wrong tool
- A damp or weeping joint at the connection the nut secures
- The nut working loose under normal vibration or heat cycling
- Damaged threads that will not take the correct torque
Before you order
- Check the appliance GC number or serial number against the compatibility list to confirm the correct fixing
- Cross-reference the alternative part number 1030903 when matching against older documentation
- Where the joint relies on a sealing washer or gasket, inspect its condition before refitting the nut
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
