What it is

The Baxi 5111915 is an M4 hex pozi special screw used to secure the gas cock assembly on a range of Baxi and Potterton gas boilers. It is a small fastening component that holds the gas cock in position as part of the appliance's gas train. It is supplied as a single screw.

Signs this part needs replacing

  • The pozi drive recess is rounded or chewed, so the screw can no longer be turned cleanly
  • The head is corroded or the thread is damaged, preventing correct torque to be applied
  • The screw is missing, leaving the gas cock insecure on its mounting
  • The screw has been removed during gas cock service and is not fit to be reused

Before you order

  • Confirm your appliance model against the fit list above, including any serial number suffix where stated
  • Check the existing screw to confirm it is the M4 hex pozi special type used on the gas cock
  • Confirm the quantity required, as the gas cock may use more than one fixing
  • Gas train components should only be worked on by a competent, registered engineer
