Cold Heading Quality Wire
Cold heading quality wire involves a particular raw material chemistry to withstand swedging, heading and forming with great quality. It is suitable for fastener and cold heading applications such as bolts, nuts, screws, rivets, nails, etc. Taubensee’s CHQ wire is manufactured by choosing particular quality raw material and drawing it to size using Taubensee’s meticulous drawing process. Following these standards allows us to keep strict control of the desired surface and chemical composition of the wire necessary for superior products in spite of demanding manufacturing processes.
The Taubensee Team is always available to discuss your steel wire specifications and needs to help you choose a type of wire best suited for your application to give you the highest performance, reliability and long life in your product.

What exactly is Cold Heading? Let’s begin by defining the general term along with the basic principles of involved in the cold heading process.
Cold Head·ing
/kōld/ /‘hediNG/
verb
Simply put: cold heading is feeding wire into a machine, cutting it into pieces, and hammering on it. The material is not heated or machined, but formed into its desired shape at room temperature. The ability to form material instead of removing it deems this process extremely efficient and cost effective when manufacturing large quantities.
At Grandeur Fasteners, we design and fabricate our own custom tooling and manufacture nearly all fastener forms including multiple upset configurations, customized head shapes, and substitutions for multi-part assemblies. Converting your supply needs to cold heading can benefit in many ways.

Cold heading (or cold forming) is a method of forming metal in progressive steps into net shaped or near net shaped parts. Starting with a slug, which is cut from a continuous coil of wire material; the cold heading machine uses a series of powerful hammers and dies to form a part. This process creates very little to no waste, offers significant material cost savings, and the volume of the starting slug is about the same as the finished part. The net volume remains the same since the material is being formed into the die, rather than cut from the blank. The cold heading process creates a stronger part, with smooth continuous surfaces while enhancing the grain flow of the material.
In contrast, metal cutting operations are typically slow and can generate as much as 60% waste.
Cold heading is more efficient than machining, allowing rapid production of large quantities while maintaining tolerances as close as +/- .002″ without secondary operations.
A progression is the process of developing gradually towards a more advanced state. Starting with the slug, each step of the progression forms the material closer and closer to its’ final shape. Intricate fasteners often require a longer progression than simple fasteners, as many simple fasteners may be completed in 1-2 blows from a cold heading machine.
Progressions are not the same for every part. Each type of fastener or component has its’ very own series of punches, dies, and hammers which have been engineered to a unique specification. Material requirements also play a role in how the progression is designed. Softer metals will form more readily (e.g. Copper, Aluminum) while harder metals (e.g. Stainless Steel, Nickel Alloy) may require multiple blows to achieve its’ final form.
Upsets and extrusions are two basic types of techniques used in cold headed manufacturing. These techniques involve the controlled forming of a material by applying enough force for the material to fill a voided space within a die. Each die is engineered accordingly, to produce the proper amount of material movement throughout the progression.
Upsets are the most common and basic technique used in cold heading today. An upset is formed when the slug is reduced in height and the starting diameter is increased. This technique is often used to create the head of the part, and may be formed with open tooling, between tooling, or enclosed tooling – depending on the upset location and shape. Integral parts may require multiple heads and diameters. To achieve these complex configurations, different upsets are incorporated throughout the part’s progression.
Another common cold heading technique is called an extrusion. There are two types of extrusions: forward extrusions, and backward extrusions.
Forward extrusions force the material through a smaller diameter orifice, thereby reducing its diameter and increasing its length. The starting material may be partially or totally contained in the tooling before the start of this type of extrusion.
Backward extrusions force material to flow around a penetrating punch or pin while being contained in a die or punch insert. This extrusion is typically used to form a hole or cavity inside a part.
Complex fasteners and components often require secondary operations to produce finished parts. These operations cannot be performed on a cold heading machine and are complimentary to the cold heading process.
Cold heading was originally created to manufacture fasteners. However, given today’s technological advancements and research, cold headed parts, fasteners, and components can be found in thousands of various products and structures around the world. This process is continuously being developed for new applications, allowing a growth in manufacturing and a reduction in cost for manufacturers.
Since 1975, we have continuously improved our process while finding new ways to help our customers reduce cost. As the leading and best cold headed supplier in the industry, Grandeur manufactures customer specific and highly specialized fasteners with unmatched quality. If your fastener or component needs require something special, whether in material or design, then Grandeur Fasteners may be a great fit for you.
