What it is
The Biasi BI1462106 is a lock-nut for Biasi gas boilers. It is a threaded fastener used to secure and lock components in place within the appliance. This part is listed under screws, nuts, bolts and clips for Biasi boiler spares.
Signs this part needs replacing
- The nut no longer holds its set position and backs off under vibration.
- Threads are stripped, cross-threaded or otherwise damaged.
- Corrosion or rust is visible on the nut.
- The component secured by the nut feels loose or moves.
- The nut flats are rounded, making it difficult to tighten or remove.
Before you order
- Check your boiler model and GC number against the Fits list.
- Confirm the part number BI1462106 is listed for your appliance.
- Inspect the failed lock-nut for thread size and condition, and compare like-for-like.
- If unsure, consult the manufacturer's parts list for your boiler.
