Signs this part needs replacing

- A hex head that is rounded off or damaged, preventing a spanner or socket from gripping
- Visible corrosion or rust on the screw, which can weaken the fixing
- A screw that has worked loose or is missing from its fixing point
- A broken or sheared screw found during inspection
Before you order
- Confirm your appliance model matches one of the Purwell Variheat models listed under Fits.
- Check that the existing fixing is M8 with a 20mm length and a hex head.
