Jim Tanner, senior VP of sales & marketing for Chicago Rivet & Machine Co., is retiring.

Tanner joined Chicago Rivet in April 2025 from M1 Concourse, where he served as COO. Prior experience also includes working as CEO for KSR International Co. in Ontario, Canada, and group president for MacLean Power Systems.

The announcement comes one month after Chicago Rivet CEO Greg Rizzo and other management for the 106-year-old fastener manufacturer reported that recurring operating losses, negative cash flows, declining revenues and reduced liquidity raise “substantial doubt” about the company’s ability to continue operating within a year, even with planned asset sales and fresh financing.

Founded in 1920, Chicago Rivet manufactures rivet setting machines, rivets, fasteners, and precision-engineered components for the automotive, heavy truck, appliance, cutlery, cooperage, HVAC, medical, furniture, and electronic industries.
