Course Overview
This course is intended to provide a high level and broad coverage of threaded fasteners. The standard course approaches each topic through the eyes of a designer or user of the fastener and the specific design implications/reasons for each decision surrounding the design of the fastener. Basic building blocks are then provided as to how to approach each of these individual design implications.
The concepts remain basic, although the materials can be customized to go into much greater depth or detail on any particular topic, if desired.
