What it is
The Alpha crossheaded screw M4 x 20mm, part number 1.034459, is a fixing fastener used in Alpha boiler assemblies. It is listed for the Alpha InTEC 2, ECO 2 and E-TEC appliance families, where it secures components within the casing and internal assemblies. The M4 x 20mm size and cross head allow it to be driven with a crosshead screwdriver during service and repair.
Signs this part needs replacing
- The cross head is rounded or damaged, so the screwdriver slips
- Corrosion or rust on the screw body or head
- Threads are stripped and the screw will not tighten
- The screw is missing or was dropped during a service
- The fixing works loose and will not hold the component in place
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the fixing point requires an M4 x 20mm crossheaded screw
- Check how many screws are needed for the job
- Confirm the head type matches the tooling you have available
