A fastener is a device used to secure two or more objects together. Fasteners can be made from a variety of materials, including metals, plastics, and composites. Each type of material has its own unique properties that make it better suited for certain applications than others.
In this blog post, you’ll get a look at some of the most common fasteners material specification information.
Metal Fasteners
Metal fasteners use the most common type of fastening material. They’re strong and durable, making them ideal for applications where a high level of strength is required.
Metals can be further divided into non-ferrous and ferrous metals. Ferrous metals, such as iron and steel, contain iron and are magnetic. Non-ferrous metals, such as aluminum and copper, do not contain iron and are not magnetic.
The most common ferrous metal used in fasteners is carbon steel. Carbon steel is an alloy of iron and carbon that is known for its high strength and low cost. Other popular ferrous metals used in fasteners include stainless steel and zinc-plated steel.
Stainless steel is an alloy of iron, chromium, and carbon that is resistant to rusting and corrosion. Zinc-plated steel is carbon steel that has been coated with a thin layer of zinc to protect it from corrosion.
The most common non-ferrous metals used in fasteners are aluminum and brass. Aluminum is a lightweight metal that is known for its corrosion resistance. Brass is an alloy of copper and zinc that has a high resistance to corrosion. It’s also softer than other metals, making it easier to thread.
Plastic Fasteners
Plastic fasteners are made from synthetic polymers such as polyvinyl chloride (PVC), polyethylene (PE), or nylon. Plastic fasteners are typically used in applications where weight or cost is a concern since they’re lighter and cheaper than metal fasteners.
However, they’re not as strong as metal fasteners, so they’re not well suited for applications that require a high level of strength.
Composite Fasteners
Composite fasteners are made from a combination of two or more materials, such as metal and plastic. Composite fasteners material specification offers the benefits of both metal and plastic fasteners while also providing their own unique set of benefits.
For example, composite fasteners are often lighter than their metal counterparts but stronger than their plastic counterparts. They also have excellent resistance to corrosive environments since they don’t rust as metal fasteners can.
