DIN standard
DIN stands for “Deutsches Institut für Normung”, meaning “German institute for standardisation”. 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.
ASTM standard
ASTM’s fastener standards are instrumental in specifying, testing, and evaluating the material, dimensional, mechanical, and metallurgical properties of the various forms of hardware fasteners. These fasteners are used to mechanically join or affix other hardware objects together, and come in many forms which include rivets, nuts, bolts, studs, screws, washers, eyebolts, nails, and threaded fasteners. These fastener standards allow hardware product manufacturers, as well as the end-users of such products, to examine and assess fasteners to ensure their strength and quality towards safe utilization.
BS standard
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 933, DIN 931 and DIN 912 being the most popular Metric fastener products in the world. When it comes to Inch washers the BS fastener standard is still in wide use.
JIS Standard
Japanese Industrial Standards(JIS) specifies the standards used for industrial activities in Japan. The standardization process is coordinated by the Japanese Industrial Standards Committee (JISC) and published through the Japanese Standards Association (JSA). Japanese Industrial Standards Committee is composed of many nationwide committees and plays vital role in standardizing activities in Japan.
ANSI Standard
Standards for dimensions and tolerances are issued by the American National Standards Institute (ANSI) in cooperation with the American Society of Mechanical Engineers (ASME) and the Industrial Fasteners Institute (IFI). Standard fasteners are basic industrial fasteners – square and hex bolts, cap screws, carriage bolts, lag screws, studs, nuts, rivets and others – which have been standardized over the years as to type‘, style, usage, properties, dimensions and tolerances. These include a vast range of sizes and types stocked by distributors and manufacturers for an almost limitless range of applications: the assembly and maintenance of vehicles, appliances, farm equipment, construction equipment, and Industrial.
GB standard
GB standards are the Chinese national standards issued by the Standardization Administration of China (SAC), the Chinese National Committee of the ISO and IEC. Mandatory standards are prefixed “GB”. Recommended standards are prefixed “GB/T” (tuījiàn). A standard number follows “GB” or “GB/T”. GB standards are the basis for the product testing which products must undergo during the China Compulsory Certificate (CCC) certification. If there is no corresponding GB Standard, CCC is not required.
