Handbook of Bolts and Bolted Joints

Presenting time-tested standards as well as validated emerging knowledge on threaded fasteners and bolted joints, this updated edition covers how to design, select parts and materials, control assembly processes, predict behavior, and solve on-the-job problems. This handbook examines key issues affecting bolting in the automotive, pressure vessel, petrochemical, aerospace, energy, and structural steel industries. The editors have successfully created a useful rather than scholarly handbook with chapters written in a straightforward, how-to manner. Theory is discussed only when necessary and the handbook's logical organization and thorough index enhance its usefulness. Handbook of Bolts and Bolted Joints, Second Edition includes updated chapters, solved numerical examples, and case studies. This new edition is an essential handbook for professionals, researchers, and students in all fields in which threaded joints are used, including automotive, aerospace, structural, chemical, and naval and ocean engineering, as well as agricultural equipment, wind turbines, and medical devices.
