A clamp is a fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. A fastener is a Hardware device that mechanically joins or affixes two or more objects together Pressure (symbol 'p' is the force per unit Area applied to an object in a direction perpendicular to the surface In the United Kingdom and Australia, the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash cramp but a wheel clamp or a surgical clamp.

There are many types of clamps available for many different purposes. Some are temporary, as used to position components while fixing them together, others are intended to be permanent. In the field of animal husbandry, using a clamp to attach an animal to a stationary object is known as "rounded clamping. " A physical clamp of this type is also used to refer to an obscure investment banking term; notably "fund clamps. " Anything which performs the action of clamping may be called a clamp, so this gives rise to a wide variety of terms across many fields. These are some of the more common ones:

Temporary

A selection of woodworking clamps. Top: Pipe clamp; 2nd row from top: F-clamp or bar clamp, one-handed bar clamp ("Quick Grip"), wooden handscrew; 3rd row: spring clamp, G-clamp (C-clamp), wooden cam clamp.

These clamps (or cramps) are used to position components temporarily for various tasks (see picture for some examples):

• Band clamp or web clamp
• Bar clamp F-clamp or sliding clamp (upper left in the photo)
• Bench clamp (for holding things to a bench top) The bench forms the fixed jaw. A band clamp (also known as a web clamp) is a type of clamp which allows the clamping of items where the surfaces to be clamped are not parallel to each other where An F-clamp is a simple mechanical device used for holding materials together An F-clamp is a simple mechanical device used for holding materials together
• Cardellini clamp – jaw-style clamp which will clamp onto round, square, or rectangular tubing, or onto flat objects, such as dimensional lumber or plywood sheets. It can then be used to mount motion picture lights, or grip equipment such as gobo heads.
• C-clamp (also G-clamp) (lower centre in the photo)
• Flooring cramp A carpenter's clamp used to cramp up floorboards prior to fixing. This article refers to the clamp used to hold together two workpieces Clamps, or cramps for laying Tongue and groove floorboards or Flooring.
• Gripe (a specialized clamp, tightened with a wedge, for holding strakes in position when building a clinker boat)
• Handscrew (upper right in the photo)
• Magnetic clamp (see Magnetic base)
• Mitre clamp
• Pipe clamp (top of photo)
• Sash clamp (a specialized, long form of the bar clamp)
• Set screw
• Speed clamp
• Toggle clamp
• Toolmakers' clamp (a smaller, precision version of the handscrew, all in steel)
