What it is

The Buderus 7100200 is a 1 inch nut supplied as a service part for Buderus gas boilers. It is a threaded fixing used to secure and seal connections within the appliance, and it belongs to the screws, nuts, bolts and clips group of boiler spares. The nut is listed for the Buderus 600-28C.

Signs this part needs replacing

  • The hex flats are rounded off, so a spanner or socket no longer grips properly.
  • Corrosion or scale has built up on the threads, making the nut difficult to remove or refit.
  • The nut has worked loose, allowing the joint it secures to weep or draw air.
  • Cracking or deformation is visible around the threads or across the body of the nut.

Before you order

  • Confirm the nut size required against the connection you are working on; this part is listed as 1 inch.
  • Check the appliance model against the fitment list above before ordering.
  • Inspect the mating thread and washer or seal, as these may also need attention once the joint is opened.
