Application Tips
1.A quick guide to screws:
a)Screws with countersunk head are mainly used for work with wood or wood-based materials. They can be countersunk flush with the surface of the workpiece.
b)Screws with a round head or fillister head are mainly used for securing fittings, signs and strips. Decoration screws are sometimes also used in furniture manufacture.
c)There are also screws with cylindrical heads and others with hexagonal heads for the socket of a screw wrench. They are used for fitting work in wooden beams.
d)Carriage bolts have a round head with a square section under the head. It is intended to prevent the bolt from turning when the nut is tightened. This bolt can only be loosened from the nut side. Carriage bolts are mainly required for woodworking.
e)Always make sure that you use the appropriate screwdriver (or wrench) for your work. If you use the wrong one, it might be impossible to remove fitted screws, meaning that if the worst comes to the worst they will be ruined.
2.A guide to drill bits – the right drill bit for any occasion. Here you will find out what each drill bit is suitable for:
a)Drilling in metal: HSS drill bits with a partially ground tip are suitable for non-ferrous metals. These include aluminium, copper, brass, zinc, iron and non-alloyed steel.
b)Drilling in wood: Brad point drill bits have a long centring tip with two pre-cutting spurs. These spurs score the wood fibres; the internal cutting edges then cut them out cleanly. Forstner drill bits, hardware drill bits or hinge cutting bits are usually used for larger drill bit diameters; there are auger bits for deep holes in wood.
c)Drilling in concrete: Masonry made of clinker, brick or concrete requires an impact drill or a rotary hammer to be used. However, if the wall consists of perforated stones with porous material, only rotary drilling is performed (i.e. without impact). The same applies to porous bricks and boarded walls. A masonry drill bit is required for all work in these materials. It has soldered-in tungsten-carbide plates on the drill bit tip.
