MacLean Curtis 

About Us / History

Curtis was founded in 1905 by Frank O. Curtis in Buffalo, NY. Mr. Curtis formed Curtis to produce and sell his five-spindle screw machine, for which his father held patents dating back to 1891. He slowly refocused the company by producing screw machined parts with his machines and served as company president from 1905 until 1917. The company started with three employees whose combined weekly wage was $11.51. 

Under the leadership of Scott Osgood, company president from 1917 until 1958, the company expanded its facility from 9000 sq. ft. to 25,400 sq. ft. New production equipment was installed and business grew substantially. 

In 1958, Harry G. Smith became the company's third president. Harry purchased a 50,000 sq. ft. building and embarked upon a 10 year expansion program. By 1970, Curtis was ranked as one of the nation's leading manufacturers of machined metal components.

 In 1978, John Hoskins was named president. He acted expeditiously to reinforce the existing high quality ethic and dedication to customer satisfaction. Under John's guidance, the company sharpened its focus on the automotive industry's needs and grew dramatically. John expanded Curtis' operations by opening a second facility in Cornelius, NC and was instrumental in landing Curtis' largest contract in history. This contract led to the opening of Curtis' third facility, located in Buffalo, NY.

Robert Squier served as company president from 1989 through 2001. Robert led the company to acquire its' fourth facility, Sheldon Precision, in Prospect, CT. The acquisition of Sheldon Precision added swiss-turning capabilities, which enables Curtis to provide screw machine parts ranging from .012" to 3.5" in diameter.

Paul Hojnacki became the 6th president in Curtis' history in January of 2002. Mr. Hojnacki joined the company in 1983 and served in various engineering, sales and operations capacities before becoming president.

In November 2014, the Buffalo, NY and Cornelius, NC facilities of Curtis Screw became a business of MacLean-Fogg Component Solutions.
