hinges
knock down fittings (KD fittings)
screws
nuts and bolts
Wood screws provide a neat, strong method of joining timber,
classified by their length, gauge (diameter), material and type of head
Woodscrews are available in four standard forms:
Countersunk – are the most common; finish flush with the surface; available plated in zinc and nickel.
Round head – usually japanned steel, and used to fix metal fittings outdoors, e.g. hinges, bolts, guttering and downpipes.
Raised countersunk – usually made of chrome-plated steel or brass, and used where appearance is important.
Twinfast – have two threads, which gives them greater holding power in manmade materials such as chipboard, MDF and blockboard.
nuts
bolts
Nuts and bolts are used to clamp two pieces of material, usually metal, together. They provide a mechanically strong method of joining materials.
Knock-down (KD) fittings are used extensively in the manufacture of flat-pack furniture.
They are ideal for use with manufactured boards such as chipboard and MDF.
Hinges are movable joints that pivot.
