About Thumb Screw Depot
Thumb Screw Depot is a small Northern Illinois business, founded in 2020, that builds stainless thumb screws with round and tee-wing plastic knobs. It does not say where the screws and knobs themselves are made.
Started by people hunting for the right part
The founders say they kept struggling to find thumb screws for their own projects. A few different sizes, colors or styles usually meant ordering from several stores, and the shipping often cost more than the parts.
ThumbScrewDepot.com opened in 2020 to put those options in one place. Its sizes run from #6-32 up to 5/16"-18, with round, oversized round, tee-wing and multi-lobe knobs, and buyers can mix sizes in one order.
Built in Illinois, parts origin unstated
The company's About page says "We build all our standard and custom thumb screws right here in the heartland of America," and every page of the site carries the line "Built In USA." It gives Northern Illinois as its location but names no town.
Built is the operative word. The knob is joined to the screw in the company's own shop, but the site does not say where the stainless steel screws or the plastic knobs are produced. So the finished thumb screw is assembled in Illinois, and the origin of its two components is not stated.
