What it is
The Worcester Bosch 87131040510 is a threaded stud with an M8 thread and a 45 mm length, supplied as a single item. It is a fixing component used in the assembly of Worcester Bosch Greenstar gas boilers, clamping mating parts together so they stay aligned and correctly loaded in service. The stud matches the thread form, length and finish of the original fixing used on these appliances.
Signs this part needs replacing
- Corrosion, pitting or surface rust on the stud, particularly where it passes through a casing or bracket.
- Stripped, cross-threaded or flattened threads that will not take a nut cleanly.
- The stud has sheared or snapped, often during removal of a seized nut.
- The clamped component has worked loose, allowing movement or a poor seal at the joint.
- The nut will not hold torque and backs off shortly after tightening.
Before you order
- Check the GC number and appliance serial plate to confirm the stud is listed for your model.
- Compare the part number against the stud being removed, and check the thread size and length match before fitting.
- Inspect the matching nut, washer or seal at the same joint and replace any that are damaged.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
