Cold Heading Fasteners

Introduction

Cold heading fasteners, also known as cold-formed fasteners, are metal parts that are manufactured using a cold forging process. The cold heading process involves shaping a metal blank by deforming it with a punch and die set under high pressure, without heating it. Cold heading fasteners are widely used in a range of industries, including automotive, aerospace, construction, and electronics.

Applications

Cold heading fasteners are used in a wide range of applications, including:

Automotive industry: Cold heading fasteners are commonly used in engine components, suspension systems, and steering components.

Aerospace industry: Cold heading fasteners are used in aircraft engines, landing gears, and wing assemblies.

Construction industry: Cold heading fasteners are used in steel structures, bridges, and other infrastructure projects.

Electronics industry: Cold heading fasteners are used in electronic devices, such as smartphones, laptops, and tablets.

Parameters

The following table lists some of the key parameters of cold heading fasteners:

Material

Cold heading fasteners can be made from a variety of materials, including stainless steel, carbon steel, and aluminum. The choice of material depends on the specific application and the desired properties of the fastener, such as strength, corrosion resistance, and conductivity.

Diameter and Length

Cold heading fasteners are available in a range of sizes, with diameters ranging from 0.5 mm to 50 mm and lengths ranging from 5 mm to 500 mm. The size of the fastener is determined by the specific application and the required strength and load-bearing capacity.

Head Type

Cold heading fasteners are available in a variety of head types, including hex, round, flat, oval, pan, truss, and more. The choice of head type depends on the specific application and the desired aesthetic and functional properties of the fastener.

Thread

Cold heading fasteners can have different types of threads, including coarse, fine, metric, UNC, UNF, and more. The choice of thread type depends on the specific application and the desired strength and load-bearing capacity of the fastener.

Finish

Cold heading fasteners can be finished in a variety of ways, including zinc plating, black oxide, plain, and more. The choice of finish depends on the specific application and the desired aesthetic and functional properties of the fastener.
