Clamp (tool) in the context of "Hand tool"

A ferrule (a corruption of Latin viriola "small bracelet", under the influence of ferrum "iron") is any of a number of types of objects, generally used for fastening, joining, sealing, or reinforcement. They are often narrow circular rings made from metal, or less commonly, plastic. Ferrules are also often referred to as eyelets or grommets within the manufacturing industry.

Most ferrules consist of a circular clamp used to hold together and attach fibers, wires, or posts, generally by crimping, swaging, or otherwise deforming the ferrule to permanently tighten it onto the parts that it holds.

A clothes hanger, coat hanger, or coathanger, or simply a hanger, is a hanging device in the shape/contour of:

• Human shoulders designed to facilitate the hanging of a coat, jacket, sweater, shirt, blouse or dress in a manner that prevents wrinkles, with a lower bar for the hanging of trousers or skirts.
• Clamp for the hanging of trousers, skirts, or kilts. Both types can be combined in a single hanger.

The clothing hanger was originally designed to allow people quick access to their clothing as well as designate an area, in their home, to keep their clothing in. It was also used to keep clothing dry or without a wrinkle.

A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.

Chucks commonly use jaws to hold the tool or workpiece. The jaws are typically arranged in a radially symmetrical pattern like the points of a star. Jawed chucks may require a wrench-like device called a chuck key to be tightened or loosened, but other jawed chucks may be tightened or loosened by hand force alone, offering convenience at the expense of gripping force. Chucks on some lathes have jaws that move independently, allowing them to hold irregularly shaped objects. More complex designs might include specially shaped jaws, greater numbers of jaws, or quick-release mechanisms.

Forceps (pl.: forceps or considered a plural noun without a singular, often a pair of forceps; the Latin plural forcipes is no longer recorded in most dictionaries) are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task. The term "forceps" is used almost exclusively in the fields of biology and medicine. Outside biology and medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps.

Mechanically, forceps employ the principle of the lever to grasp and apply pressure.
