I was impressed by the Scherr family’s commitment—Dubuque Screw Products—to a quality work environment for many in the Dubuque area. This family company and the apprenticeship program they have will be instrumental to the growth in Dubuque for years to come.

-Lt. Gov. Kim Reynolds,


I was approached by Matt Scherr, Operations Manager of Dubuque Screw Products, to assist them in the development of a comprehensive Safety Program for their organization. I was very impressed with the company’s commitment to the development of a Safety Program and the energies they put into the development of this program. Due to their commitment and dedication, their Safety Program was implemented very quickly and the company now has a very high focus on worker safety in their organization.

-Jim Poe, Program Manager III, Iowa State University-Center for Industrial Research and Service


Dubuque Screw Products is a great company to work with and a trusted partner in the manufacturing of IBI SCIENTIFIC’s quality life science products. They consistently supply IBI with quality parts in a timely manner, and have shown the capability to provide solutions to non-traditional types of parts and services.

-Engineer/Manufacturing Manager, IBI SCIENTIFIC,


I work with over 50 vendors/suppliers as a buyer for GE.
Dubuque Screw Products is by far the best one to work with.
I never have to worry about quality issues because we never have any with them. Always prompt to get with you when placing order or if you are just asking a question. Always willing to go the extra mile for you. They are a A+ business to work with and you will not be sorry doing business with them.

-Buyer, Eli Bridge Company,


Lt. Gov. Kim Reynolds and I visited Dubuque Screw Products back in November 2015 and were impressed by their commitment to quality and service. Dubuque Screw Products is an example of the type of Iowa business we are proud to support and watch grow in Iowa.

-Gov. Terry E. Branstad,


I have been conducting business with DSP for eight years. They are a professional company that understands the nature of business and what it takes to help their customers succeed in their own business. The entire staff is friendly and ready to help. I would recommend DSP to anyone who needs a quality product.

Thank you.
