Founded in 1946 and based in the stockyards of Chicago’s West Side, ATF began as a supplier of surplus World War II military fasteners. From this humble beginning the company has grown and transformed itself into a global manufacturer of precision cold-formed and machined components and assemblies.  ATF has steadily enhanced its manufacturing capabilities, building a reputation for innovative products, superior quality, highly capable processes and best-in-class customer service.  Today, ATF is a leader in the design and manufacture of tight-tolerance metal components, assemblies and engineered fasteners.  The company remains a family business built on entrepreneurial passion and team spirit.

In early 2009, ATF began interviewing several Chicago banks to replace its long-standing banking relationship which was being adversely affected by the challenges in the automotive industry.  Although ATF had not initially contacted Wintrust, in 2Q09 Wintrust completed two creative equipment financing arrangements and began to provide treasury management solutions for related family businesses.  Through these dealings, ATF recognized Wintrust’s entrepreneurial approach, commercial lending capabilities, and dedication to the middle market.   ATF then invited Wintrust to participate in the bid for its full banking relationship.  Wintrust and its experienced commercial lenders put together a customized loan package that quickly gained the attention of the ATF management team.   In December 2009, ATF and Wintrust (through the collaboration of North Shore Community Bank and Wintrust Business Credit) closed on a comprehensive credit facility including full cash management services.   ATF now has the financial support to continue to be a market leader and innovator.
