Cold Drawn Bars Built for Aerospace & Defence Fasteners
In the aerospace and defence sectors, fasteners are more than just components - they are mission-critical elements that ensure safety, reliability and operational integrity. A single fastener failure can have serious consequences, from compromising aircraft performance to jeopardising the structural integrity of defence vehicles and naval equipment.
​
That’s why leading manufacturers rely on precision cold drawn bars from Offshore Stainless, designed to meet the toughest specifications and deliver consistent, high-performance results.
Precision Cold Drawing for Critical Applications
The cold drawing process is central to producing bars that meet the stringent requirements of aerospace and defence fasteners. Whether machining round or hexagon bars, working with long lengths or creating bespoke specifications, our bars are engineered for accuracy, repeatable performance and tight tolerances.
This process enhances mechanical properties such as yield strength, tensile strength and ductility, providing components that withstand extreme stresses encountered in critical applications.
Fasteners made from our cold drawn bars are used in a range of demanding environments: aircraft assembly where vibration, pressure changes and fatigue are constant factors; defence vehicle construction, including armour and structural frameworks; naval and subsea systems, where corrosion resistance and load-bearing strength are essential; and missile and aerospace propulsion systems, where extreme temperatures and precision fit are non-negotiable.
In every scenario, the integrity of the fastener directly impacts safety, performance, and reliability. With over 1,000 tonnes of cold drawn bar in stock, part of our 3,000-tonne overall inventory, Offshore Stainless Supplies has the capacity to support continuous production without compromise. Our bars are tailored to match precise mechanical properties, ensuring that every fastener performs reliably under critical service conditions.
High Standards, Superior Performance
Meeting industry standards is essential, but true performance goes beyond certification. Offshore Stainless Supplies is the only UK manufacturer approved to supply UNS 32760 Super Duplex strain-hardened bar to NORSOK MDS D59/D59L Rev 3. This globally recognised certification demonstrates our commitment to delivering materials that perform in extreme, high-stakes environments, providing engineers and manufacturers with confidence in material integrity.
Our cold drawn bars also deliver enhanced machinability, higher strength, and improved fatigue resistance, allowing manufacturers to achieve better throughput, longer tool life and smoother finishes on their fastener products. Reduced rejects and rework mean faster, more efficient production while maintaining the highest levels of performance for critical aerospace and defence applications.
Trusted Expertise for Aerospace & Defence
With over 20 years of experience and exports to more than 70 countries, Offshore Stainless has established itself as a trusted partner for fastener manufacturers operating in the most demanding sectors.
Whether your fasteners are destined for airframes, subsea control systems, military vehicles or propulsion assemblies, make sure they are built from material you can trust.
