Mid-West Fastener Association Introduction (Incorporated 1946) A membership with connections that hold the world together, the Mid-West Fastener Association is one of the oldest fastener associations in the United States. For over 70 years, the association has expanded and evolved from a small local group, to the largest regional fastener association in the industry with members from coast to coast. The Midwest market has the largest concentration of fastener related firms in the USA. MWFA activities have drawn members, as well as the fastener industry at large, to our dinner meetings, Educational Seminars, annual Fastener Expo & Trade Shows, the industry’s largest Golf Outing, and many other programs, from all over the world.
