Fastener Safety Technical Manual
This book is not about the design of a joint, but how to recognize potential problems, assemble and repair the connection safely. It describes the many types of variables that cause fastener failures; what happens mechanically when a fastener is tightened and addresses what brings it to failure even though you followed procedures.
