This comprehensive course is prepared in such a way to benefit engineers from all disciplines since fasteners are utilized in a variety of applications. Selecting the proper fastener material for the specific environment and application shall be an easier task upon completion of this course. Fastener materials shall be discussed along with the following topics:
Platings and coatings used to provide corrosion protection
Precautions to take when plating high strength fasteners
Fastener properties and testing methods
Strength grading system and identifications
Galling and seizing
Manufacturing techniques and possible defects that may form
Installation torques and clamping loads
Locking methods to avoid loosening
Potential fastener failure mechanisms
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
At the conclusion of this course, the student will:
This course is intended for structural, mechanical and civil engineers.
Benefit for Attendee
Attendees of this course will not only become knowledgeable about the factors to consider for selecting the right type of fastener for the application, but also the most critical factors to consider during installation to avoid premature failures.
Most people think the selection of fasteners (bolts, nuts, etc.) is a simple task. In reality it is rather complicated and could result in catastrophic failures if consideration is not given to factors such as corrosion, temperature, dynamic loading (fatigue), vibration and initial preload. This course is intended to cover sufficient data on topics such as bolting materials, coatings and installation torques to enable all fastener users to make informed decisions regarding proper selection for a particular application.

Strength, operating temperature, corrosivity, vibration and fatigue loading are the main factors to be considered in selecting the right fastener for the application. Knowing which critical characteristics to consider, taking proper precautions during fastener manufacturing and processing, and defining the proper installation methods are key to eliminating or reducing the susceptibility to premature failures once the mechanical joint is placed in service.
