What it is

The Nut M30 is a threaded fixing nut supplied by Potterton for its commercial boiler range. It is listed against model 115 - 930 kW and is used to secure M30 threaded connections on the appliance. The nut forms part of the boiler's mechanical assembly, where a correctly matched thread and seating face are needed to hold the joint tight.

Signs this part needs replacing

  • The nut will not hold torque and works loose after tightening
  • Visible corrosion, pitting or material loss on the nut or its threads
  • Cross-threading or damaged thread form preventing correct seating
  • Weeping or leakage at the joint the nut secures

Before you order

  • Confirm the M30 thread size matches the connection on your appliance
  • Check the boiler model and kW rating against the fitment listing
  • Inspect the mating stud or fitting for thread damage before reassembly
