About this Course
Since their mass production and standardization became possible in the late 18th century, threaded fasteners have played a large role in industry.
The strength, versatility, ubiquity, and low cost of threaded fasteners has resulted in their use in everything from structural supports for buildings to the bolts used to mount a motor to its base.
While relatively simple in design and construction, selecting the proper fastener can be a very important choice. Many industrial disasters and fatalities have been attributed to a poorly chosen or defective fastener.
By the end of this course, you will be able to:
Define the major terms relating to screw threads
Discuss the various classes of fit
Describe thread specifications for unified and metric threads
Explain the various mechanical properties of threaded fasteners
Discuss the advantages and disadvantages of different fastener materials
