What it is
The Nut H M6 is a metric M6 hex nut manufactured by Saunier Duval, part number S1045800. It is a small fastening component used on Isotwin Condens and XEON Condens appliances, where it secures threaded connections and mounted assemblies within the boiler. It is supplied as a pack of 10.
Signs this part needs replacing
- The nut is missing after a service or repair, leaving a fixing point incomplete
- Corrosion or rust on the nut body or threads
- Rounded or damaged hex flats that will not take a spanner cleanly
- Cross-threaded or stripped internal threads
- A joint that will not pull down tight, indicating the nut is no longer holding torque
Before you order
- Confirm your appliance model against the fit list above
- Check that the fixing point requires an M6 thread before ordering
- Check how many nuts are needed for the job, as this part is supplied in a pack of 10
- Inspect the mating stud or bolt for thread damage, as a worn stud will not hold a new nut correctly
