Leading Cold Headed Fastener Manufacturers

Cold heading, or cold forming, is a production process used to create fasteners and other specialty parts quicker and more effectively than other manufacturing techniques. This process creates various headpiece tools, including screws, shoulders, and fasteners. Compared to screw machining, cold heading is superior because there is less scrap produced through this process. Compared to screw machining, this process results in significant savings on raw materials. Cold heading also raises the performance of the product. Cold heading reorganizes the grain structure, enhancing shear strength performance and avoiding disruptions to grain flow. Read More…

Cold Headed Fasteners Cold headed fasteners are joining mechanisms used in a variety of industries that are typically formed using the cold heading process. While traditional metalworking uses heat or cutting to adjust the shape of a metal blank, cold forming or cold working uses high pressure from a hydraulic press or ram to force a piece of metal into a pre-formed die. The force exceeds the elastic properties of the material in order to deform it into the desired shape.

cold headed fasteners

Cold heading results in higher quality over other manufacturing processes since the smoothness and dimensions of a die are directly transferred to a product’s surface. This quality eliminates the need for secondary finishing procedures associated with other manufacturing techniques and, as a result, costs associated with parts, labor, inspection, tolerance issues, and purchases are all reduced.

Cold heading creates the potential to reduce multi-part assemblies to single-part assemblies. Cold heading also creates tight tolerance consistency throughout the manufacture of an item. Therefore, cold heading can be used as a combination of primary and secondary machining to achieve part configurations where a tighter tolerance, above and beyond what is typically required, may be needed.

Cold-Headed Fastener Production

Cold heading is a multi-step production process that creates metal objects while they are still at room temperature. Cold heading uses a series of hammers and dies to form metal without heating it. Cold heading begins, however, with a drawing machine which pulls a thick coil of wire through a blank. The material is compressed to the desired diameter by the drawing machine. The blank is struck inside the cold heading machine between a punch block and a die, forcing the material into the die and resulting in the desired shape.

Cold-Headed Fastener Manufacturing Processes

There are the two fundamental processes utilized in cold-headed manufacturing, upsets and extrusion. These techniques involve applying sufficient pressure to cause a material to fill a void inside a die. Each die is designed appropriately to ensure the proper amount of material movement during the process.

Cold Heading Upsets

Upsets are currently the most widely utilized and fundamental cold-heading technique. An upset results from decreasing a slug's height while increasing its starting diameter. This method is frequently employed to construct a part's head, and depending on the upset position and shape, it may be formed with open tooling, between tooling, or enclosed tooling. In addition, upsets are used as a means to form integral components featuring various heads and diameters. Additional upsets with intricate arrangements may also be included at various stages of a part's development.


Extrusion is another popular cold-heading method. Extrusions can be classified into two categories: forward extrusion and backward extrusion. Forward extrusions reduce the material's width and length by forcing it through an aperture of a lower diameter. Compression is produced by forward extrusion because the cavity of the two dies is smaller than the diameter of the wire. The starting material may be completely or partially contained in the tooling before this extrusion starts.


A hole or cavity is made with backward extrusion by forcing metal through a punch in the opposite direction. Backward extrusions urge the material inside a die or punch insert to flow around a sharp punch or pin. In most cases, backward extrusion is utilized to create a hole or cavity inside a part.

Cold-Headed Fasteners Applications

Cold heading was traditionally used to create pieces like simple fasteners. Due to continual technical advancements, cold heading can now be used to manufacture highly-specialized fasteners and specialty components. These fasteners include specialist bolts, fasteners used in the production of automobiles, and fasteners used in electronics.

Advantages of Cold-Headed Forming

  • Items are created with tight tolerances leading to greater precision.
  • Fasteners are produced at high production rates.
  • Cold-headed forming allows for a large volume of capacity.
  • Cold-heading forming results in a reduced waste of raw materials.
  • Cold-headed forming results in enhanced physical characteristics for the items produced.
  • Cold-headed forming results in cost savings when compared to machining.
  • Cold-headed forming allows for the capability to produce fasteners with a wide range of diameters.
  • A customer's demands can be followed while creating both standard and non-standard configurations.
  • Typically, secondary procedures are not required to finish fasteners created through cold-headed forming.

Disadvantages of Cold-Headed Fasteners

Despite the advantages provided for fasteners created through cold-headed forming, there are some disadvantages to be made aware of. Pieces must be formed with more force with cold-headed forming due to the absence of heat. Although dies may be less expensive, the necessary equipment required to produce parts is larger and more expensive.

The parts must also be thicker than in machining because hammers can only squeeze so much metal into a given place. Some materials cannot be utilized in a cold-heading machine, while harder metals may take repeated hits to fill a die. Cold heading machines cannot do rolling, stamping, or bending operations. Therefore, more complex parts will require different processes than cold-headed forming.

Choosing the Correct Cold Headed Fasteners Manufacturer

To make sure you have the most beneficial outcome when purchasing Cold Headed Fasteners from a Cold Headed Fasteners Supplier, it is important to compare at least 4 Suppliers using our Cold Headed Fasteners directory.
