What it is

This is a Sime TCB screw, size M4 x 10 mm, with a zinc-plated finish. It is used in Sime gas boilers, including the Friendly Format and Super MKII ranges, for securing internal components.

Signs this part needs replacing

  • Visible corrosion or rust on the screw head or threads.
  • The screw head is rounded or damaged, making it difficult to turn.
  • Threads are stripped or worn, preventing a secure hold.
  • The component it secures is loose or vibrating.
  • The screw cannot be tightened to the required torque.

Before you order

  • Confirm the part number 2005101 matches your requirement.
  • Check the screw size (M4 x 10 mm) and thread type (TCB) against the existing screw.
  • Verify your boiler model is listed in the Fits section.
  • Ensure the zinc-plated finish is suitable for the application.
