Tri Part Screw Products, Inc.

Tri Part Screw Products was started in the Spring of 1981. The business was started with three people, four B&S screw machines and 1,500 sq ft of manufacturing space. Our roots were all from the original Slick Electro, manufacturers of aircraft magnetos and ignition systems for small piston engine aircraft. We managed the contract machining side of this business, before starting Tri Part.

We quickly outgrew our space which led to building our state of the art facility in 1991. We now have over 20,000 sq ft and more than 50 employees working at Tri Part. We are bursting at the seams again and are discussing our next expansion!

Our equipment list’s from Wickman Multi-Spindle Screw Machines to the latest in CNC Swiss Automation and CNC Grinders.
