EPSP has been producing high quality parts and sub-assemblies for over 60 years. We serve the aerospace industry for both civilian and military applications. Aside from aerospace, we produce components for air valve manufacturers, precision tool and gage manufacturing and custom automobile parts. In the medical field we manufacture parts for skull surgery and cornea transplants.

Founded in 1943 by Harold Aseltine and his son Howard Aseltine, Extreme Precision Screw Products (EPSP) started out in a small wooden building in the middle of a local junk yard near Davison Road and Dort Highway in Flint, MI. The shop was originally set up with machinery that made firing pins for the 50-caliber machine guns during World War II.

In 1951 EPSP moved to 1838 Remell St. in Flint, Michigan, where it remains today. With additions built to accommodate new machinery and business expansion, the complex has sprawled to over 16,000 square feet.

With its 25-30 employees, Extreme continues to specialize in components for the aerospace and military industry with diversification into medical components, firearm sights & grip screws, precision tool & gaging, and some custom automotive parts.
