What it is
The Alpha 1.023009 is an M5 x 55 mm socket head cap screw. It is a threaded fixing used on Alpha gas boilers, including the CD and Intec families. The socket head allows tightening with a hex key.
Signs this part needs replacing
- The hex socket is rounded or stripped, preventing the key from gripping.
- The screw is corroded or seized in the thread.
- The screw has been dropped or lost during servicing.
- The threads are damaged or the screw will not tighten correctly.
- The screw head is deformed or sheared.
Before you order
- Confirm your boiler model and GC number against the fitment list.
- Check the thread size and length required for the fixing point.
- Check how many screws are needed for the repair.
- Inspect the existing screw to confirm it is the correct type before ordering a replacement.
