What it is

The Cross Head Tapping Callor Screw is a fixing component manufactured by Andrews for use in their water heaters and Fastflo appliances. It is a cross head tapping screw, identified by part number Z346. This screw is used to secure components within compatible Andrews units.

Signs this part needs replacing

  • The cross head is stripped or rounded, preventing the screw from being tightened or removed.
  • Corrosion or rust is visible on the screw head or threads.
  • The screw is missing or has worked loose from its fixing point.
  • The screw no longer holds the component securely in place.

Before you order

  • Check your appliance model against the fit list above to confirm compatibility.
  • Inspect the existing screw to confirm it is a cross head tapping type.
  • Verify the required quantity, as more than one screw may be needed for the repair.
