The Mamsco Advantage

Our low overhead allows us to pass savings on to you. All lumber yards and “big box” stores buy their collated nails and fasteners from master distributors who buy containers from overseas. Mamsco buys our containers direct from overseas, cutting out the middleman and passing the savings directly on to you. Mamsco is one of the few companies where you have direct access to the owner every day. Our owner Ann Marshall for over 30 years of experience buying and selling fasteners and tools to contractors. We are not constrained by the typical “corporate mentality”. We have the ability, flexibility, and creativity to find a way to get it done. Mamsco is proud to be a woman owned small business. Mamso is fully certified by the State of Connecticut Department of Administration Services Supplier Diversity Program, as a Woman Owned Small/Minority Business Enterprise. That is the Mamsco Advantage.
