Q

State two knock-down (KD) fittings

A
  • Modesty block
    • small, rigid polymer blocks. They have moulded holes that take screws
    that are used to join blocks to panels and could be used on cupboards
    and storage units
  • Barrel nuts and bolts
    • uses a cross-dowel that is fitted into one of the pieces to be joined. The
    bolt is inserted through the other piece of timber and tightened into the
    cross-dowel (often using an Allen key). They are often used in bed frames
  • Cam-lock connector
    • consist of a metal dowel that is screwed into one of the pieces. The cam
    is a disk that fits into a pre-drilled hole. When the disk is rotated with a
    screwdriver, the collar on the dowel locks into the cam and pulls both
    pieces tightly together. They are used in flat-pack furniture such as
    bookcases, where the horizontal shelves are attached to the sides
    4) Wood screws
    - are used for screwing two pieces of wood together where the thread is
    needed only at the bottom. When joining two pieces of wood together,
    the top part is drilled with a clearance hole that the screw simply pushes
    through. The bottom piece of wood has a pilot hole (thinner than the
    thread) so that the thread bites into the timber
    5) Coach bolts
    - are used to join wood pieces together. Under the domed head of the
    bolt is a square piece that digs into the wood when tightened, preventing
    the bolt from rotating. They are used for fitting door locks or in street
    furniture such as wooden benches
