Baxi Screw M6 x 15mm Dog Point 633912

The Baxi 633912 is an M6 x 15mm dog point screw used as a fixing in Baxi and Potterton gas boilers. The dog point (a short unthreaded pilot nose) lets the screw locate into a hole before the thread engages, which helps when fitting into blind or aligned fixings. It is supplied as a gas boiler spare in the screws, nuts, bolts and clips category.

• The screw is missing from its fixing position, leaving a component or cover loose.
• The head is rounded or chewed, so it can no longer be tightened or removed cleanly.
• The thread is stripped, cross-threaded or damaged, so it will not hold torque.
• Corrosion or pitting on the screw body, common where it sits in a damp or flue-adjacent area.
• The screw has been reused too many times and no longer seats the part it secures.

• Confirm your appliance model against the manufacturer's parts list before ordering.
• Check that the fixing position requires an M6 x 15mm dog point screw, as other lengths and point types are used elsewhere on these appliances.
• Check how many screws are needed for the job, as this listing is for the screw only.
• Inspect the mating thread or captive nut for damage before fitting a new screw.
