What it is
The Baxi 607939 is an M3 x 8mm Taptite screw used in Baxi gas boilers. Taptite screws form their own thread as they are driven, so they are typically used to secure components and covers where a self-threading fixing is specified. It is listed across a wide spread of Baxi combi and system boiler families.
Signs this part needs replacing
- The screw is missing from its fixing point, leaving a cover or component unsecured
- The head is rounded or chewed, so the screw can no longer be driven or removed cleanly
- The thread has stripped in the parent material and the screw will not tighten
- A panel or bracket is loose and rattling in service
- The screw shows corrosion or damage where it passes through a mounting point
Before you order
- Confirm the part number 607939 against your appliance's parts list
- Check your boiler model and, where applicable, the serial number range shown in the fit list
- Verify the thread size and length required at the fixing point before fitting
- Check how many fixings are needed if more than one is being replaced
