DIN 976 (preplaces DIN 975) Technical Specifications
This standard covers stud bolts with threads produced to tolerance 6g which is customary for bolt/nut assemblies of thread engagement group N as specified
Metric DIN 976 Fully Threaded Stud Bolts are headless bolts threaded all the way from one end to the other (full / all thread). They are designed for a nut to be applied on both ends and are often used for electrical, construction and plumbing for hanging purposes. Aspen Fasteners offers one of the most complete ranges of metric studs and other inch and metric industrial fasteners for immediate delivery from stock. The following sizes of metric DIN 976 Fully Threaded Stud Bolts are available for immediate shipping from stock: Diameters ranging from M2 to M52 and lengths to 1000mm in A2 and marine grade A4 stainless steel.
DIN (Deutsches Institut für Normung – German Institute for Standardization) standards are issued for a variety of
components including industrial fasteners as Metric DIN 939 double end studs. The DIN standards remain common in
Germany, Europe and globally even though the transition to ISO standards is taking place. DIN standards continue to be
used for parts which do not have ISO equivalents or for which there is no need for standardization.
