Dyson Corp manufactures a wide range of critical application fasteners for the Military, Heavy Construction, Infrastructure, Hydropower, Mining, Renewable Energy, and General Manufacturing markets. Our products are 100% domestic manufactured from USA poured or DFARS compliant materials and qualify for Buy America projects. With in-house forging, heat treating, machining, assembly, and inspection capabilities, you can rest assured fasteners from Dyson will be on-time and to print. We pride ourselves on exceeding our customers expectations!

Our products range in size from 1″ to 24″ in diameter, and are as long as 60′! We manufacture both internally and externally threaded fasteners, and sell large diameter nuts and bolts as matched sets to confirm thread-fit.
