Temporary joining methods
Nuts and bolts
Nuts and bolts are used to clamp two pieces of material, usually metal, together. They provide a mechanically strong method of joining materials.
Bolts are available with hexagonal and square heads. Bolts have a parallel thread
Nuts are screwed onto bolts and provide the clamping force. They are available as hexagonal but are also available as square, wing and locking.
Wing nuts are designed to be tightened and undone by hand. Locking nuts are used to prevent the nut becoming loose due to vibration
Knock down fittings
Used a lot in flat-pack furniture. Ideal to be used with manufactured boards. Offer higher efficiency and accuracy than drilling jigs
Wood screws
Woodscrews are classified by their length, gauge (diameter), material and type of head (philips/slot/etc,).
Woodscrews have a tapering thread that comes to a point. They are cheap and come in a few forms
Countersunk
To make the screw flush with surface
Round head
Raised countersunk
Twinfast
Straight slots
Crossed slots
