What it is
The Worcester Bosch 87161029920 is a 20 mm stud with a hex head, supplied as a fixing for Worcester Bosch heating appliances. It is a threaded fastener that holds a component in position, with the hex head allowing it to be driven or held while a nut is run onto the exposed thread. It is used across the Greenstar Heatslave II range, including the ErP and EXT variants.
Signs this part needs replacing
- Visible corrosion or rust on the stud or its thread
- A rounded, chewed or otherwise damaged hex head that will not take a spanner cleanly
- The stud shears or strips during removal of the component it secures
- The fastener no longer holds torque and the joint works loose
- Weeping or staining around the joint the stud clamps
Before you order

- Confirm the length and thread of the stud being replaced, as the 20 mm stud is shared across several Heatslave II variants.
