Steel pins are small cylindrical metal parts used as fasteners in a broad range of applications. They are typically produced using the process of cold heading and may be used to align, locate, position, fix or conjoin two or more components.

Steel Pin Design
Steel pins can be carbon steel or stainless steel, and are made from steel wire which is fed through a punch and die in order to form the desired shape. Cold heading, or cold forming, is a process used to create simple metal parts without using heat to alter the shape of the metal. Unlike traditional metal working processes, cold forming uses high pressure and force to change a metal blank into a desired shape or product. The force needs to exceed the elastic capabilities of the material in order to cause the deformation. Steel pins are used for many purposes, often in the tailoring, fashion, upholstery, and furniture industries and can vary greatly in terms of size and strength. Cold heading is not always practical for the manufacture of complex parts, but it is an economical solution for producing simple parts like steel pins. The process makes efficient use of the raw material as there is minimal wastage and hardly any scrap produced.
Things to Consider When Purchasing Steel Pins
The heads on the steel pins can be adjusted to their applications and can range in size from less than an inch to a number of inches in diameter and the pin can also vary greatly in length. The body of the pin itself can be evenly cylindrical, or tapered at one end. It is important to consider these factors with regard to the intended application of the pin to ensure mechanical functionality and a sturdy enough component. Stainless steel is commonly used because of its corrosion resistance and its high levels of durability. As cold headed fasteners are often required for heavy duty applications in harsh environments, stainless steel pins are an ideal product to use. The process of cold forming changes the properties of some materials especially in terms of increasing the yield strength of a metal and creating a dense and porous free product. This is a beneficial change for pins used in industrial or construction processes which will be required to bear a joining load relative in weight to their size. There are several different types of pins, including linch pins, locating and fixture pins, hitch pins, cotter pins, spring pins and dowel pins.
