Double HH Manufacturing

What Double HH Manufacturing does

Double HH Manufacturing is a privately held, Iowa-based manufacturer of heavy-duty hitchpins, agricultural linkage components, and precision-machined industrial hardware, founded in 1973 in Rock Valley. The company pioneered the heavy-duty hitchpin with a red plastisol coated head and wide grip handle, which remains its signature product category and brand anchor more than five decades later. Its product portfolio spans five core lines — hitchpins (including Lockease safety, T-handle, swivel-lock, wire lock, and zinc-plated variants), linkage parts for 3-point hitch systems (clevises, drawbars, lift arms, top links, quick hitches, PTO adapters, lynchpins, stabilizers), general hardware (cotterpins, retaining rings, grease fittings, O-rings, machinery keys, fasteners), power transmission components (hubs, sprockets, pulleys), and kits/assortments — supplemented by in-store retail display programs, custom-imprinted hitchpins, and custom CNC machining services.

The company's core technology is precision machining of metal hardware components, with proprietary know-how centered on the red plastisol coating process for grip and corrosion resistance. Manufacturing operations are concentrated at a single Rock Valley, Iowa facility, with capabilities spanning standard catalog production through bespoke CNC machining.

Commercially, Double HH operates a strictly B2B distribution model, selling exclusively through qualified distributors, manufacturers, and farm stores — including Bomgaars, Theisens, Runnings, Fastenal, True Value, Campbell Supply, Wilco, and Lockridge. The company does not sell directly to end consumers, with revenue generated through one-time product sales into agricultural equipment, heavy-duty truck/hitch OEM, and industrial/metal fabrication customer segments. Marketing is limited to a product catalog website and a Facebook presence, and the company is supported by a social-impact partnership with Hope Haven, Inc. focused on employment for individuals with disabilities.
