Applications of our parts

specially machined parts by West Special Fasteners are trusted across a variety of industries:

Offshore and marine industries

Our corrosion-resistant machined components are engineered for reliability in marine and saltwater conditions. Offshore environments—exposed to seawater, salt spray, high humidity, and sub-zero temperatures—demand parts that resist corrosion while retaining mechanical strength. We specialise in specially machined parts using exotic alloys such as Inconel, Monel, and Super Duplex, delivering high-performance solutions for critical applications in the harshest conditions.

Construction and infrastructure projects

Our high-strength specially machined parts are trusted in structural applications across bridges, tunnels, and complex infrastructure projects. From skyscrapers to subsea installations, structural integrity relies on components that offer consistent performance under load. Precision-machined for maximum tensile strength and durability, our custom parts are ideal for load-bearing and safety-critical environments where failure is not an option.

Chemical plants and power generation

Our non-standard machined components are manufactured from acid-resistant and high-strength alloys, making them essential for pumps, valves, and reactor systems. In environments where extreme pressure, temperature, and chemical exposure are constant, reliability is paramount. These components are designed and machined to withstand aggressive conditions while maintaining precise performance and integrity over time.

Renewable energy

Our specially machined components are deployed in wind turbines, solar frameworks, and wave energy installations—engineered to endure harsh outdoor conditions and fluctuating loads. Built for long-term durability and environmental resistance, these custom parts support the structural and operational integrity of renewable energy systems, from offshore wind farms to coastal solar arrays.

Defence

Our specially machined parts are trusted across a range of non-weapon military applications, including armoured land vehicles, naval vessels, and auxiliary systems. Engineered for exceptional strength, resilience, and long-term reliability, these components play a vital role in assembly, maintenance, and operational readiness, ensuring performance in mission-critical defence environments.

Mining

Our custom-machined components are essential in the mining industry, delivering the strength and durability needed for heavy equipment operating in abrasive and extreme environments. Whether for mineral processing machinery, structural supports, or underground systems, our parts are designed to withstand intense mechanical stress and harsh conditions, ensuring performance and longevity in the most demanding applications.

Specially machined parts manufacturing capabilities

At West Special Fasteners, we excel in delivering precision-machined components tailored to complex project specifications. Whether it’s intricate geometries, exotic materials, or bespoke finishes, our team ensures each component is produced to the highest standards, backed by ISO 9001 certification and full production traceability.

Advanced precision machining

Our modern UK facility is equipped to handle diverse and demanding machining requirements with:

  • CNC, conventional and automatic lathes – For tight-tolerance machining on custom components.
  • Hydraulic presses – Ideal for shaping tough alloys and non-standard profiles.
  • Thread rolling machinery – To create high-integrity threads on specialist parts.
  • Drilling and milling machines – For intricate features and detail work.
  • Vertical machining centre with 4th axis – Enabling complex, multi-dimensional machining in a single setup.

We specialise in machining high-performance alloys, including Inconel, Monel, Duplex, and Super Duplex, for industries such as nuclear, marine, renewables, and defence. Every part is inspected at each stage of production, and we provide comprehensive documentation and quality control records, ensuring complete confidence in material properties and performance.
