In the design, assembly, quality assessment and standardization of threaded fasteners and joints, expressions are frequently used which relate to the various torque functions which are required to be applied or assessed. Much confusion is generated by the multiplicity of terms used throughout industry. As a basic reference document providing a comprehensive list of terms, this glossary is intended to promote better understanding between the various sections of industry and the users of fasteners.
Many of the definitions in this glossary are essentially the same as those used in other British Standards already published. As these British Standards are revised and new standards are produced, the use of the definitions given in this glossary will be encouraged in order to promote wider acceptance and recognition of standard terminology.
In this glossary, terms are arranged in alphabetical order. In the definitions, italics have been used to indicate terms that are defined elsewhere in this glossary.
