Fastener Engineering & Prototyping


With experienced customer service specialists, we can take care of all your custom fastener needs even in the absence of a blueprint or other specific details. Chicago Nut & Bolt can either design a one-of-a-kind fastener or help you to choose an appropriate one from our large inventory. To ensure rapid prototyping, we stock blanks in different styles and sizes, including socket head cap screws, structural bolts, hex flange bolts, and carriage bolts. We stock a variety of other unified, threaded, and metric fasteners as well.

Our fastener prototypes comply with your specifications for geometry, joint design, and structure. We also provide assistance in material selection to suit the temperature variation, corrosion, and vibration resistance requirements of your applications. Prototypes can also be finished with different options, such as plating or painting. As we offer a full range of flexible fastener supply services, no order is too small or too large to command our full attention. Whether it is one piece or a million pieces, prototype or production, Chicago Nut & Bolt delivers.
