Duplex Bolts and Duplex Screws
Bespoke duplex bolts and duplex screws manufactured for industries that require exceptional strength and corrosion resistance.Commonly used across sectors such as oil & gas, marine engineering, chemical processing, and heavy industry, duplex fasteners are designed to perform reliably in demanding environments where standard materials may not provide the required durability.
Duplex stainless steels combine high mechanical strength with strong resistance to corrosion, making them well suited to applications exposed to moisture, chemicals, or extreme operating conditions. We manufacture duplex bolts and duplex screws in a variety of sizes, thread types, and configurations to suit your specific project requirements.

For applications that demand even greater performance, we can also supply components manufactured as a super duplex fastener. A super duplex fastener provides enhanced corrosion resistance and higher tensile strength, making it particularly suitable for offshore, subsea, and highly corrosive environments where long-term reliability is essential.
Quality and traceability are central to every product we manufacture. Each batch undergoes thorough inspection and quality control to ensure consistency, performance, and compliance with recognised international standards such as DIN, ASTM, and BS. We can also manufacture duplex components directly from customer drawings or bespoke technical specifications.
Our duplex fasteners are widely used in critical assemblies where reliability is vital. From securing pipeline systems and structural components to supporting equipment operating in aggressive environments, duplex bolts and duplex screws provide dependable fastening where failure is not an option.
With flexible lead times and responsive service, we support projects ranging from rapid prototypes to large production runs. Our experienced team can assist with material selection and technical guidance to ensure the correct solution for your application.
