The fastener parts are a hardware device that mechanically joins or affixes two or more objects together. Fasteners can also be used to close a container such as a bag, a box, or an envelope; or they may involve keeping together the sides of an opening of flexible material, attaching a lid to a container, etc. There are also special-purpose closing devices, e.g. a bread clip. Fasteners used in these manners are often temporary, in that they may be fastened and unfastened repeatedly. Ever Hardware provides custom-made fastener parts and customizable packaging.

Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners.

Cold forming is the process of forging metals at near room temperatures.
In cold forming metal is formed at high speed and high pressure into tool steel or carbide dies. The cold working of the metal increases the hardness, yield, and tensile strength.
The cold heading process used is similar but specifically refers to the upsetting of a volume of metal into a head like on a nail or screw.
Cold Forming and Cold-Heading processes are flexible. Parts can be hit multiple times while staying in one die (“one die, multiple blows”), or transferred from dying to die to progressively form various geometries (“multi-die forming”). Cold Forming consistency is excellent because each part is made in the same die. The material is used at almost 100% efficiency. There is no scrap as found in machining. Because of the high productivity, the efficiency of material use, and the use of precise dies, cold headed and cold-formed parts have significant cost and quality advantages.
