ASME

American Society of Mechanical Engineers

ASME has standards for fasteners that are similar to both ANSI and ASTM. The standards similar to ASTM cover dimensional, chemical, and mechanical properties and are often preceded with an S. For example, ASME SA193 is similar to ASTM A193. The following ASME standards are dimensional standards and are often used to call out the type of the fastener in engineering prints similar to ANSI standards.

BS

British fastener standards became obsolete many years ago but are still in use in the fastener market and the Fastener after market. British standards for fasteners should have been overtaken by ISO standards in fasteners and EN standards in fasteners but in practice the German DIN standards became the fastener market leaders.

DIN

DIN stands for “DeutschesInstitutfürNormung“, meaning “German institute for standardization”. National standards (DIN) will be/have been largely replaced by international/European standards. DIN standards are still valid for products having no ISO or EN standards. DIN standards that begin with “DIN V” (“Vornorm”, meaning “pre-issue”) are the result of standardization work, but because of certain reservations on the content or because of the divergent compared to a standard installation procedure of DIN, they are not yet published standards.
