The following types of anchoring are usually found:

Entre los diferentes tipos de unión se pueden considerar la unión de forma, [8]​ la unión de fuerza y la unión con elementos de unión. También existen las uniones que emplean combinaciones de las anteriores.

Los elementos de unión, anclajes o similares son piezas auxiliares que permiten la unión de dos o más piezas formando un conjunto (que integra las piezas).

Threaded connecting elements

A threaded union element has an external or internal thread.[9]​ The most common types are the cargol, and the femella, with the presence of a flywheel.

Other, more specialized threaded joint elements, including presoner threaded joint element, cargol, threaded insert and threaded bar.

Other anchor variants include the following:.

When selecting a screw for industrial applications, it is important to consider a variety of factors. The threading, the load applied on the screw, the rigidity of the screw and the number of screws required must be taken into account.

When choosing a screw for a given application, it is important to know the details of that application to help select the proper material for the intended use. Factors that should be considered include:.

Historically, for example, American screws, bolts and nuts were not fully interchangeable with their British counterparts and therefore did not fit properly into British equipment. This, in part, helped develop numerous United States Military Standards and specifications for the manufacturing of virtually any piece of equipment used for military or defense purposes, including screws. World War II was a major factor in this change.

A key component of most military standards is traceability. Simply put, material manufacturers must be able to trace their materials back to their origin and provide traceability of their parts entering the supply chain, typically using barcodes or similar methods. This traceability is intended to help ensure that the correct parts are used and quality standards are met at every step of the manufacturing process; Furthermore, in this way inferior quality parts can be traced back to their origin.[33]​.

As an example, in 2005, the United States screw industry was estimated to operate 350 manufacturing plants and employ 40,000 workers. The industry is strongly linked to the production of automobiles, aircraft, household appliances, agricultural machinery, commercial construction and infrastructure. More than 200 billion screws are used in the United States annually, 26 billion of them in the automotive industry. The largest distributor of screws in North America is Fastenal Company.[34]​.
