What it is

The Navien bind head Taptite screw is a threaded fastener used on Navien NCB-CE and NPE boiler appliances. It has an M4 x 12 thread and is manufactured in STS410 material. It secures panels, brackets and internal components where a Taptite thread-forming fixing is required.

Signs this part needs replacing

  • The fixing will not tighten and keeps turning in the parent material.
  • The head is rounded, chewed or sheared, so the screw cannot be driven or removed.
  • Visible corrosion or surface damage on the screw.
  • Threads are stripped on the screw or in the hole it seats into.
  • A fastener is missing after servicing, leaving a cover, bracket or panel unsecured.

Before you order

  • Confirm the thread size and length required: M4 x 12.
  • Check the head type and drive against the fixing being replaced — bind head Taptite.
  • Confirm the material specification, STS410, is suitable for the location.
  • Match your appliance model against the fitment list above.
