Cold Formed Fasteners Specialty External Threaded Forging Components

The cold formed fasteners are made by cold-forming progress. 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. Ever Hardware provides custom-made cold formed fasteners and customizable packaging.

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.
The range of possible shapes is rather broad, including heads, threads, steps, knurls, chamfers, grooves, undercuts, and tapers.
Some features that cannot be directly made with Cold Forming or Cold Heading can be added in secondary operations, such as threading, pointing, or rolling.
Typical parts made using cold forming technology include screws, nuts, and bolts, electrical contacts, and rivets. In addition to these “high volume standard” parts, there are many thousands of different custom parts for a diverse set of applications.
