Screws are often used to join materials, such as chipboard, MDF and natural woods. There is a type of screw called a 'self-tapping' screw, that can be used to join metal sheet. Screws are ideal for joining materials either permanently of 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.
