Bolts are essential hardware for binding two or more objects together, commonly found in various industries such as construction and manufacturing. With the advances in technology and innovation, different types of Bolts have emerged, including non-metallic and composite bolts. These new bolts are incredibly useful in certain applications, and it’s important for professionals and enthusiasts alike to understand the differences between them. This blog post will dive deep into the differences between non-metallic and composite bolts.

What is Non Metallic Bolt?

A non-metallic bolt is a fastener that joins two or more objects together. It is usually constructed using a material such as nylon, fibreglass or composite materials and typically does not contain any metal elements. Non-metallic bolts come in various shapes, sizes and threading options, making them ideal for more specialized applications than traditional metal bolts. They are also used where electrical conductivity is necessary, as the absence of metal eliminates the potential for electrical interference with other components.

What is Composite Bolt?

A Composite Bolt is a threaded fastener that combines two or more materials, such as steel and aluminium, to increase its strength and improve its corrosion resistance. The bolts are commonly used in applications with desired characteristics of high tensile strength, vibration dampening, or temperature insulation. Composite Bolts have been designed to be lightweight yet capable of withstand extreme weight-bearing conditions without failure. Due to their unique properties, these bolts have also been used for various other applications.

Difference Between Non metallic Bolt and Composite Bolt

Material Composition

The primary difference between non-metallic and composite bolts is their material composition. Non-metallic bolts are made from ceramics, plastics, or glass. On the other hand, composite bolts are made of two or more materials – typically consisting of a reinforced plastic or resin material and carbon or fiberglass fibers.

Durability and Strength

Regarding durability and strength, composite bolts are much stronger and more durable than non-metallic bolts. Composite bolts can be engineered to meet specific design requirements, making them much stronger than non-metallic bolts. Although still strong, non-metallic bolts may be more prone to wear and tear, which could eventually lower its overall strength.

Corrosion Resistance

Another key difference between non-metallic and composite bolts is their resistance against corrosion. Non-metallic bolts are highly resistant to corrosion and decay, making them ideal for applications exposed to caustic materials and extreme weather conditions. Composite bolts, while still corrosion-resistant, may not resist the same level of deterioration as non-metallic bolts.

Cost Efficiency

Overall cost is a significant factor when it comes to selecting non-metallic bolts or composite bolts. Non-metallic bolts are generally less expensive than composite bolts due to the raw materials involved. Composite bolts, on the other hand, have higher material and manufacturing costs, resulting in a higher price point.

Applications

Non-metallic bolts are commonly found in applications where weight is a priority, such as the aerospace or automotive industry. Since these bolts are much lighter than traditional metallic bolts, they can help reduce fuel consumption and overall weight. Composite bolts, on the other hand, are commonly found in applications where the strength and durability of the bolt are critical, such as wind turbine blades, aircraft parts, and other high-stress applications.

Conclusion:

In summary, both non-metallic and composite bolts have pros and cons. Non-metallic bolts are lightweight, cost-efficient, and are highly resistant to corrosion. Composite bolts, on the other hand, have superior strength and durability, making them ideal for applications that require high-stress or loads. When considering which bolt to use, evaluate the application’s needs. By selecting the proper hardware, you can ensure your project or application runs smoothly and efficiently.
