Producing Fasteners and Precision Components
For nearly a century SPS Technologies has built its world class reputation for excellence on one basic block: a dedication to producing fasteners and precision components to meet your most exacting requirements.
From design assistance and material selection to statistically monitored manufacturing processes, the Aerospace Fasteners staff is committed to satisfying our customers' needs
Since the first generation of propeller-driven aircraft SPS Technologies has been a major supplier of fasteners to the aerospace industry
Today, it's hard to find an aircraft that doesn't use SPS fasteners. They can be found in engines, wings, fuselages, and landing gear. At SPS we pride ourselves on our ability to satisfy all your high performance fastener requirements Turn to SPS for all-metal locknuts and bolts, non-metallic insert locknuts and precision components in a variety of materials and platings; in diameters up to 3" and lengths up to 48"
At SPS Technologies we believe that Aerospace is a quality level, not a market. Unlike many other aerospace manufacturers in North America, our aerospace fasteners are used by a substantial customer base not involved in the aerospace market. Markets such as medical technologies, high performance engines used in automobile racing, marine applications and gas turbine engines used in power generation demand Aerospace quality fasteners in their applications
Anticipating your needs is what we do best at SPS Technologies. We recognize the importance of having the infrastructure to deliver solutions. Our facilities accommodate forging extruding, tapping, milling, grinding, computer-controlled heat treating, automated plating as well as many secondary operations. Plus, SPS has an advanced quality management system in place that tests every stage of production. Every SPS product meets industry and customer specifications as well as the SPS internal manufacturing standards. SPS Aerospace Fasteners have only one quality level - the quality level you demand
Quite simply, we provide a combination of engineering knowledge, design ingenuity, manufacturing and testing ability and systems capability that knows no equal
It is our pledge to continuously raise our standards. Through continuous improvement programs, we constantly challenge our manufacturing capabilities to improve our product quality and our lead times so we can continue to offer you the best overall value in the industry.
SPS' product offering and investment strategy is focused on technically sophisticated components and materials that are necessary and vital to key end-user markets such as aerospace, transportation, power generation, racing, farm and construction equipment and general industrial. Common characteristics include:
Market Leader in Most Product Niches
In most product niches, SPS is either the leading manufacturer or one of the two or three leading manufacturers. Proprietary Metals and Fastening Technology A major emphasis on product development has resulted in the creation of many high temperature, high tensile, corrosion resistant and other special property materials, which have been designed to meet very demanding customer specifications.
State-of-the-Art Forging and Machining Technology
Significant investment in forging and machining tool equipment coupled with sophisticated tool and die design has led to the development of many proprietary manufacturing processes, which enable SPS to provide customers with unique solutions to their product performance problems.
Excellent Quality Control Programs
Quality control programs of all SPS businesses reflect the demanding requirements of SPS' aerospace heritage. All product lines benefit from the culture of quality that has a long history at SPS. Because of this culture and our strong product design capability, many of SPS' products are manufactured for safety-critical applications.
Sophisticated Systems
SPS' computer systems house an expansive library of parts that are a significant resource for the Company and its customers. For many of these part numbers, SPS has been the only manufacturer or the dominant manufacturer.
