All of the founders of CadParts have a Design Engineering background. They understand the importance of having an accurate model and having enough engineering properties associated with the model to allow engineering to compare part specifications with the design requirements i.e., clamp force, tensile strength, torque, head size, etc. This model and engineering properties allow the design engineer to verify fit, form, and function.
All of the parts are modeled to allow the parts to be shown in the assembled state. For example, the lock washers are modeled in the flat form so that the fastener height above the clamp surface is accurately shown.
With our Design Engineering background, we understand the importance of communicating the design to others. Our part descriptions are adequate for purchasing to purchase the parts. A hex headed bolt is not just a hex headed bolt, but the material, grade, and plating are specified on the bill of material.
