Screws are used to fit materials such as chipboard, MDF and natural woods together although there is a type of screw called a self-tapping screw that can be used for joining thin metal sheet. screws can be used to join materials together permanently although as they can be unused with relative ease they are also good as a way of fixing materials temporarily.

 

COUNTERSUNK - SLOT HEAD: This can be used for general woodworking for example fitting hinges to doors. Because the screw is countersunk it can be tightened 'flush' to the surface of the material.

 

POZIDRIV HEAD: Used with special screw drivers which will not slip when pressure is applied. This is ideal when using screws in corners or confined spaces.

 

ROUND HEAD SCREW: These are used for fixing pieces of material together where countersunk holes are not being used. Round head screws can look quite decorative especially if they are made of brass.
