What it is
The Andrews Z422 is a cross head bind screw for Andrews water heaters. It is a small fastening component used in the assembly and servicing of the Fastflo and hot water spares ranges.
Signs this part needs replacing
- The cross head is stripped or rounded, so the screw can no longer be driven or removed
- Corrosion or rust on the head or thread
- The screw is missing or has worked loose from its fixing point
- Thread damage preventing it from tightening down
Before you order
- Check your appliance model against the fit list above
- Confirm the head type and thread match the screw being replaced
