What it is
The Andrews Z343 is a cross head tapping collar screw for Andrews water heaters. It secures the tapping collar, the fitting that connects pipework to the appliance. This is a small consumable part, often replaced during servicing or repair.
Signs this part needs replacing
- Corroded or rusted screw head
- Cross head rounded or damaged, making the screw difficult to turn
- Threads stripped so the screw will not tighten
- Water weeping from around the tapping collar
- Tapping collar loose or failing to seal
Before you order
- Confirm your appliance model against the fitment list above
- Check the head type and thread match the screw being removed
- Note how many screws are required for the job
