What it is
The Andrews Z411 is a cross head screw with an S tight collar, used as a fixing on Andrews water heaters. The collared head spreads load and holds the fixing tight against the component it secures. It is a small consumable part intended for maintenance and repair work on the appliance.
Signs this part needs replacing
- Rounded or chewed cross head that will not take a screwdriver
- Corrosion or rust on the screw head or collar
- Stripped or worn threads that will not tighten
- Loose fixing allowing the secured component to move
- Water weeping past a joint held by the screw
Before you order
- Check your appliance model against the fit list above
- Compare the screw with the one removed — head type, thread and length
- Confirm how many screws are needed for the repair
