Our History
Manufacturing machine keys, taper pins and precision fasteners since 1872. Every product meets the exacting demands of USA and military specifications.
1872
Precision Beginnings & Resilience
Founded by Charles Merrick in Fallston, PA, Standard Horse Nail Company was built on pioneering manufacturing techniques—including an innovative hot-forging process developed alongside Erastus Pierce that set new industry standards. When a devastating fire swept through the original shop, Merrick’s determination shone through. He relocated to New Brighton, PA, constructing the historic facility that remains our manufacturing home today and laying the foundation for over 150 years of continuous American production.
Early 1900s
Engineering for the Automotive Revolution
As horseless carriages began replacing horses, the founder’s nephew—Silas Merrick, an M.I.T.-trained engineer—saw the massive potential in the emerging transportation industry. To support this boom, Silas developed a groundbreaking gang-milling method that enabled the mass production of specialized half-moon keys. This engineering breakthrough kept assembly lines moving, cemented our role in the automotive supply chain, and successfully steered the company toward high-precision industrial hardware.
1960s to Present
Domestic Precision Leaders
Recognizing shifting global markets, Stanho strategically phased out horse nail production in the 1960s to specialize entirely in high-accuracy fasteners. Today, operating as a multi-generational family-owned business, we stand as one of the nation’s leading domestic manufacturers of machine keys, woodruff keys, taper pins, cotter pins, ground dowel pins, and custom precision parts—delivering the high-volume capacity and uncompromised quality that modern industry demands.
Leadership Built on Tradition
In an era of impersonal corporate conglomerates, Stanho remains family-owned and operated across two generations:
- Robert S. Merrick Jr., Chairman of the Board
- Ryan Merrick, President
- Peter Merrick, V.P. of Operations
Our family heritage ensures every order receives the direct attention, quality assurance, and reliability our customers have relied on since 1872.
