What it is

The Potterton 5142495 is an M6 x 16mm screw with a serrated flange head, supplied as a pack of 10. It is a fixing used on Potterton Commercial Sirius 2 and Sirius 3 FS series boilers. The serrated underside of the flange bites into the mounting surface to resist loosening under vibration.

Signs this part needs replacing

  • Corrosion or rust on the screw head or thread
  • Rounded or chewed head that will not take a driver or socket cleanly
  • Stripped or flattened threads that will not torque down
  • Flange damaged or flattened, reducing grip on the panel
  • Fixings missing after a service or panel removal

Before you order

  • Confirm the thread size and length (M6 x 16mm) against the fixing being replaced
  • Check the appliance model against the fits list above
  • Note that the screws are supplied as a pack of 10
