What it is
A recessed pan head screw manufactured by Potterton under part number 612857. It is a No.4AB x 9.5 mm (3/8 inch) fixing used across a range of Potterton gas boiler assemblies. The screw secures panels, covers and internal components where a low-profile recessed head is required.
Signs this part needs replacing
- The screw head is stripped or rounded, so a driver no longer grips it
- Corrosion or rust on the screw body or head
- The screw is missing after a service or panel removal
- A cover or panel is loose because the fixing will not tighten
- The screw has snapped, leaving the shank in the thread
Before you order
- Confirm your boiler model against the fitment list above
- Check the existing fixing is a No.4 x 3/8 inch (9.5 mm) recessed pan screw
- Check how many fixings are required, as this listing is for the screw only
- Verify the thread and head type match the position being secured
