What it is

The Worcester Bosch 87161550450 is an M4 x 16mm Pozi pan head Taptite screw. Taptite screws form their own thread as they are driven, making this a thread-forming fastener for the Worcester Bosch gas boiler models listed below. It is a service part intended for repair and maintenance work on those appliances.

Signs this part needs replacing

  • The Pozi recess is rounded or chewed and the driver bit slips
  • Corrosion or rust is visible on the head or thread
  • The screw turns freely and will not tighten because the thread has stripped
  • The screw is missing, loose or has sheared during removal

Before you order

  • Check your boiler model against the fit list above
  • Confirm the thread size and length match the screw being replaced
  • Inspect the mating thread in the component for damage
  • Confirm how many screws the job requires
