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. |
