Temporary joining methods
Screws
Woodscrews provide a neat, strong method of joining timber,
classified by their length, gauge (diameter), material and type of head.
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.
Always screw through the thin piece and into the thick piece.
Drill a pilot hole slightly smaller than the core in the thick piece.
Drill a clearance hole in the thin piece, slightly larger than the shank of the screws.
Countersink the clearance hole.
Nuts and Bolts
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.
washers
Washers are used to spread the load and protect the surface when the nut is tightened.
Knock Down Fittings (KD fittings)
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
Hinges are movable joints that pivot.
