After the material selection process, the next step in the production process of fasteners is to draw the wire. Wire drawing is a metalworking process that involves reducing the diameter of a metal rod or wire by pulling it through a series of dies. This process is used to improve the surface finish, mechanical properties, and dimensional accuracy of the wire.

There are two main types of wire drawing: cold drawing and hot drawing.

  1. Cold drawing: Cold drawing is the most common type of wire drawing used in the fastener industry. It involves pulling the wire through a series of dies at room temperature, which results in a smoother surface finish, improved mechanical properties, and tighter dimensional tolerances. Cold-drawn wire is typically used for applications where high strength and precision are required.
  2. Hot drawing: Hot drawing is a less common type of wire drawing used in the fastener industry. It involves heating the wire to a temperature above its recrystallization point and then pulling it through a series of dies. Hot drawing is used for materials that are difficult to cold-draw, such as stainless steel or high-alloy steel. Hot-drawn wire is typically used for applications where high strength and ductility are required.

The purpose of wire drawing in the fastener industry is to produce wire with a consistent diameter, a smooth surface finish, and precise dimensional tolerances. This wire is then used to produce fasteners such as bolts, nuts, screws, and washers. At Gofast, we use both cold drawing and hot drawing techniques to produce wire that meets the specific needs and requirements of our customers in the fastener industry.
