What it is

The Ariston 570316 is a flange screw with an M8 thread and a 20mm length. It is a fixing component used on Ariston gas boilers and water heaters, where flange-headed screws secure mating parts and covers. The flange spreads the clamping load across a wider contact area than a standard hex head.

Signs this part needs replacing

  • Visible corrosion or rust on the screw head or thread
  • Rounded or damaged head that will not take a socket or spanner cleanly
  • Screw missing after a service or repair, leaving a joint under-clamped
  • Thread stripped or cross-threaded, so the screw will not torque down
  • Weeping or staining at a flange joint that the screw secures

Before you order

  • Confirm your appliance model and edition against the fit list above
  • Check the thread size and length of the screw being replaced
  • Check how many screws are needed for the joint or cover being refitted
  • Confirm the screw is not supplied as part of a larger assembly on your model
