Fasteners are different in Dimensions, Configurations, Thread Forms, Strength Levels, ability to Resist Corrosion, Behavior in Elevated or Low Temperature, etc. However, the main function of a Fastener is to achieve a desired Clamp Load on a specific Bolted Joint.
The key objectives of selecting the appropriate Fastening System are:
Achieving Fasteners compatibility (Grades, Property Class, Thread Fit, etc.)
Achieving compatibility between Joint materials and fastening components.
Ease of assembly.
Considering Loosening Prevention features and techniques.
Minimize overall cost.
When selecting a fastening system for a particular application, it is crucial to determine the joint type, whether it is a Tension Joint, or a Shear Joint.
In both the tension and shear joint designs, some level of tension in the bolt and resulting compression in the clamped components is essential to the joint integrity.
The most important joint elements to examine are the Clamp Load (Grip,) Thread Tensile Area, Nominal Diameter, Threaded Length in Grip, Unthreaded Length in Grip, Nut Thickness, and Washers Material, Thickness, Diameter, and configuration.
Additionally, Washers act as spacers, distribute load, reduce wear, lock bolts (lock washers,) and increase preload (spring, wave, and conical washers.)
