Applications of Our Hex Bolts

Hex bolts manufactured by West Special Fasteners are trusted across a variety of industries:

Offshore and marine industries

Our corrosion-resistant hex bolts are ideal for marine and saltwater applications. Offshore environments, characterised by constant exposure to seawater, salt spray and high humidity, freeze cold temperatures, require fasteners that resist corrosion while maintaining strength. Our expertise in exotic alloys like Inconel, Monel, and Super Duplex ensures that our hex bolts perform reliably in such conditions.

Construction and infrastructure projects

Our high-strength hex bolts are used in structural connections for bridges, tunnels, and large-scale construction projects. 
From bridges to skyscrapers, structural integrity depends on high-quality fasteners. Our hex bolts are manufactured to provide exceptional tensile strength, making them ideal for load-bearing and safety-critical applications.

Chemical plants and power generation

Manufactured with acid-resistant and high-strength alloys, our non-standard hex bolts are critical for pumps, valves, and reactors. Used in extreme environments where high pressures, temperatures, and chemical exposure are commonplace. They are designed to withstand these stresses while maintaining performance.

Renewable energy

Our hex bolts used in wind turbines and solar installations, designed to withstand environmental stresses. Our custom hex bolts are used in wind turbines, solar installations, and wave energy projects, where durability and environmental resistance are crucial.

Defence

Our hex bolts are widely trusted in a variety of non-weapon military applications, including land vehicles, naval vessels, and auxiliary systems. Designed for strength and durability, our hex bolts are critical in assembly and maintenance.

Mining

Our hex bolts are essential components in the mining industry, providing the strength and durability required for heavy-duty equipment and harsh operational environments.
