Engineering drawing abbreviations and symbols

Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies.

Technical standards exist to provide glossaries of abbreviations, acronyms, and symbols that may be found on engineering drawings. Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 and ISO 128 are two of the standards. The ISO standard is also approved without modifications as European Standard EN ISO 123, which in turn is valid in many national standards. Australia utilises the Technical Drawing standards AS1100.101 (General Principals), AS1100-201 (Mechanical Engineering Drawing) and AS1100-301 (Structural Engineering Drawing).
