What are fasteners?<\/strong><\/h2>\n\n\n\nFasteners are essential components in any industry, designed to join parts, structures or components either temporarily or permanently. Also known as cold formed fasteners<\/strong> or cold headed fasteners<\/strong> depending on the manufacturing method used, these elements ensure that assemblies hold together, support loads, resist vibrations and meet strict design specifications. From the construction of a building to the assembly of an electronic device, fasteners are the foundation that guarantees stability, safety and proper functioning across countless products and industrial systems. <\/p>\n\n\n\nTheir proper choice is crucial to the durability and performance of the final assembly, so their precise and robust manufacture, such as that offered by cold heading, is of vital importance.<\/p>\n\n\n\n
Materials most commonly used in the manufacture of fasteners by cold heading<\/strong><\/h2>\n\n\n\nOne of the most important factors in the manufacture of fasteners<\/strong> is the choice of material.<\/p>\n\n\n\n\n- Cold heading steel<\/strong>: provides hardness, mechanical strength and durability, making it perfect for high load bearing fasteners.
<\/li>\n\n\n\n- Aluminum cold heading<\/strong>: offers light weight and corrosion resistance, characteristics highly valued in sectors such as automotive, electronics or light construction.
<\/li>\n<\/ul>\n\n\n\nThe choice between steel or aluminum depends on the final application: while a steel screw can guarantee structural safety, an aluminum screw reduces weight without sacrificing efficiency.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nTypes of common fasteners<\/strong><\/h2>\n\n\n\nScrews<\/strong><\/h3>\n\n\n\nScrews are threaded elements designed to attach to a material, creating an internal threaded joint or coupling with a nut. They are characterized by a threaded shank and a head that allows torque to be applied for insertion or removal. They are essential for temporary or permanent assemblies, offering great versatility in the industry. <\/p>\n\n\n\n
Nuts<\/strong><\/h3>\n\n\n\nNuts are parts with an internal thread that attach to the threaded shank of a screw or bolt. When turned, they exert pressure against the clamping surface, securing the connection between components. They come in various shapes and designs, including safety variants to prevent loosening due to vibration. <\/p>\n\n\n\n
Rivets<\/strong><\/h3>\n\n\n\nRivets are permanent fasteners that join two or more parts together through plastic deformation of one or both ends. Once installed, they cannot be removed without damaging the rivet or the bonded materials. They are widely used in applications where high mechanical strength and an immovable bond are crucial. <\/p>\n\n\n\n
Pins<\/strong><\/h3>\n\n\n\nPins are cylindrical or tapered elements that are inserted into matching holes to align, position or fix components. They are often used to transmit shear forces or to prevent relative movement between parts. Their simple design makes them ideal for precision applications or as safety features. <\/p>\n\n\n\n
Washers<\/strong><\/h3>\n\n\n\nWashers are flat pieces, usually circular, which are placed under the head of a bolt or nut. Their main function is to distribute the clamping load over a larger surface area, protecting the part material and preventing loosening. There are also lock washers designed to resist vibrations. <\/p>\n\n\n\n
Bolts<\/strong><\/h3>\n\n\n\nBolts are cylindrical fasteners without threads along their entire length or with threads at one end, designed to be used with a nut. They are usually more robust than bolts and are used in joints where higher tensile and shear strength is required. They are common in construction and heavy machinery. <\/p>\n\n\n\n
