What it is

A truss head screw with a Phillips (+) drive, sized M4 x 10 and manufactured in STS410. It is supplied by Navien for use on NCB-CE system and combination boilers. The wide, low-profile truss head spreads clamping load across the fixing point, making it suited to securing panels and components where a flush finish is needed.

Signs this part needs replacing

  • The screw is missing from its fixing point, leaving a panel or component loose.
  • The Phillips drive is chewed or rounded, so the screw cannot be tightened or removed cleanly.
  • Corrosion or surface pitting on the head or thread.
  • The screw has worked loose through vibration and no longer holds its fixing.
  • The thread is stripped or damaged, preventing it from gripping.

Before you order

  • Confirm the fixing requires an M4 x 10 screw.
  • Check that a truss head with a Phillips (+) drive suits the recess or panel being secured.
  • Verify your appliance model against the fitment list above.
  • Check how many screws are needed for the repair before ordering.
