Additional Information

Adhesive joint strength is fundamental to the attachment strength of an adhesive bonded fastener. The adhesive bond strength is a function of a number of variables: the strength of the fastener, the surface area of the fastener, the fastener material and finish, the adhesive selected, the thoroughness of the adhesive mixing, the time elapsed between adhesive mixing and application to the bond surfaces, the temperature during adhesive cure, the application of constant pressure (fixturing) during adhesive cure, the surface preparation of the substrate, the substrate material and finish, and the thickness of the substrate. The key to consistent adhesive bonding is controlling the process. (Click Bond Process Specification CBPS206 outlines the recommended materials and process for adhesive bonded fasteners.)

Other design factors include the environment (temperature, humidity, etc.) the joint will be exposed to, the type of loading (tension, shear, torque, vibration, etc.), the maximum load, the desired safety factor, the weight of the fastener, and the labor cost for installation.
