What it is
The Worcester Bosch 87161156830 is an oval-head screw with an M5 x 22mm thread, supplied as a single unit. It is a fixing component used within Worcester Bosch gas boilers, where it holds panels, brackets and internal assemblies securely in position so the appliance continues to run as designed. The oval head sits flatter than a standard countersunk or pan head, which suits the recessed fixing points found across the Greenstar and British Gas ranges.
Signs this part needs replacing
- A fixing point that no longer holds, leaving a panel, bracket or internal component loose
- Vibration or rattling from a cover or assembly that should be clamped tight
- A rounded or chewed head that will not take a driver, usually after a previous removal
- Visible corrosion, pitting or thread damage on the screw shank
- A screw that has been dropped or lost during a service or strip-down
Before you order
- Check the appliance GC number and model against the compatibility list before ordering, as the same screw is used across several Greenstar and British Gas variants
- Confirm the existing fixing matches the M5 x 22mm oval-head pattern and that the alternative number 1022063 does not already appear on your parts record
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
