What it is

The Baxi 633909 is an M4 x 16mm dog point screw, supplied as a boiler spare for Baxi and Potterton gas appliances. The dog point tip allows the screw to locate and start cleanly in a tapped hole before the thread engages. It is used as a fixing within the appliance assembly.

Signs this part needs replacing

  • The screw is missing from its fixing position after servicing
  • The head is rounded or chewed, preventing correct torque to be applied
  • The thread is stripped or cross-threaded in the tapped hole
  • Corrosion or heat damage has weakened the screw
  • The screw will not tighten down and the component it secures remains loose

Before you order

  • Confirm the part number 633909 against your appliance's parts list
  • Check your boiler model against the fitment list above
  • Verify the thread size and length required at the fixing point
  • Check whether any other fixings are missing from the same assembly
