MALLETS

A mallet is a kind of hammer , often made of rubber or sometimes wood , that is smaller than a maul or beetle, and usually has a relatively large head. The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel. Mallets are used in various industries, such as upholstery work, and a variety of other general purposes. It is a tool of preference for wood workers using chisels with plastic, metal, or wooden handles, as they give a softened strike with a positive drive. Wooden mallets are usually used in carpentry to knock wooden pieces together, or to drive dowels or chisels . A wooden mallet will not deform the striking end of a metal tool, as most metal hammers would. It is also used to reduce the force driving the cutting edge of a chisel, giving better control. Hardwood mallets are also used to knock in cricket bats . Copper , brass and leaden mallets are typ...

Calipers Read in another language Watch Edit Caliper detail view A caliper ( British spelling also calliper, or in plurale tantum sense a pair of calipers) is a device used to measure the distance between two opposite sides of an object. Many types of calipers permit reading out a measurement on a ruled scale, a dial, or a digital display. But a caliper can be as simple as a compass with inward or outward-facing points. The tips of the caliper are adjusted to fit across the points to be measured and then the caliper is then removed and the distance read by measuring between the tips with a measuring tool, such as a ruler . It is used in many fields such as mechanical engineering , metalworking , forestry , woodworking , science and medicine .

Wrench types, Torque wrench

Torque wrench Read in another language Watch Edit A Torque wrench torque wrench is a tool used to apply a specific torque to a fastener such as a nut or bolt . It is usually in the form of a socket wrench with special internal mechanisms. A torque wrench is used where the tightness of screws and bolts is crucial. It allows the operator to set the torque applied to the fastener so it can be matched to the specifications for a particular application. This permits proper tension and loading of all parts. A torque wrench uses torque as a proxy for bolt tension. The technique suffers from inaccuracy due to inconsistent or uncalibrated friction between the fastener and its mating hole. Measuring bolt tension (indirectly via bolt stretch) is actually what is desired, but often torque is the only practical measurement which can be made. Torque screwdrivers and torque wrenches have similar purposes and mechanisms.
