Heavy Construction and Infrastructure

Helping Build America With Domestic Made Fasteners & Forgings

Dyson manufactures a wide range of domestic fasteners, forgings and machined components used in a variety of heavy construction and infrastructure projects throughout the USA. From heavy hex nuts used in the construction of highway guardrails, signs, and light poles, to specialty length heavy hex bolts used to erect sound deadening walls along highways, Dyson products have truly been holding America together since 1884! Our products are additionally used in the construction of bridges, locks & dams, seawalls, and in retrofitting critical pipeline infrastructure. 

Dyson is an approved manufacturer of “100% Melted and Manufactured in the USA” nuts for State Departments of Transportation. We manufacture dual-certified Heavy Hex nuts to 2H/DH as well as DH3/7 specifications. These nuts are manufactured of domestically poured steel in our Painesville, Ohio factory and qualify for Buy America projects. We stock these items in sizes ranging from 1 ½” through 4” and can custom manufacture sizes up to 26” in diameter.
