This textbook teaches the user how to create tolerance stacks using the ‘Two Column’ method. The book teaches how to establish a stack path, ground out the parts, and create a stack using all geometric characteristics. Fundamental concepts of GD&T are reviewed when introducing each characteristic.

It includes examples of specific stacks that should be done for a bolted joint with fixed fasteners. It also has a special focus on stacks to determine “do the bolts fit through the holes” with fixed fasteners and floating fasteners with various different levels of assumptions. All examples and exercises include complete, detailed solutions.
