For over 125 years, we’ve supplied domestic fasteners, forgings and machined parts to America’s transportation infrastructure of bridges, railroads and waterways, the industries of renewable energy generation and mining, shipbuilding and nuclear power and the OEM supply chain.  Beginning in 1884, as a specialty forge shop in Cleveland, founder Joseph Dyson began producing small forgings for various industries. Responding to customer demand, Dyson soon developed the capability to manufacture larger fasteners and forgings, as well as fork lift arms for the material handling industry.  Today, forgings made at the Painesville, Ohio plant range in size from 1/2 to 10,000 pounds. Equipment includes a combination of hammers, mechanical and hydraulic presses, upsetters, benders, and state-of-the-art hot part formers with in-line heat treating.  In addition, the company’s extensive CNC turning and milling operations, and the considerable thread rolling, drilling and tapping capability; have helped us develop into a premier critical fastener manufacturer.  Working in product diameters from 3/4 to 8 inches, we produce fasteners to various specifications, including ASME, MIL, ANSI and DIN, and service critical component markets, such as our military contractor and naval shipyard customers.
