What it is
This is a Worcester Bosch brass screw supplied as a single fixing for the manufacturer's Greenstar range of gas boilers. It falls under the clips, screws and springs group of boiler spares, the small retaining hardware that holds covers, brackets and internal components in position. The screw is a service item: it is removed and refitted during routine strip-downs and can be lost, cross-threaded or corroded over the life of the appliance.
Signs this part needs replacing
- The screw head is rounded or chewed, so a driver no longer bites cleanly
- The thread is stripped or cross-threaded and the screw will not torque down
- Corrosion or scale on the brass body makes removal difficult or leaves the fixing seized
- The screw has been dropped during a service and cannot be recovered
- The component it retains is loose, rattling or sitting proud of its mounting
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct fixing
- Confirm the part number 87161124100 or the alternative number 1021731 before ordering
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
