DIN 975

Threaded Rods

Scope and Field of application

DIN 975 Threaded Rods Threaded rods are generally supplied in nominal lengths of 1000 mm and can be cut into sections if different lengtlis and tolerances on length are required by the customer. They can also be used as double and studs with a nut on either side, or as studs. Tolerance class 6g specified for the thread is commonly used for bolted connections and applies to thread engagement group N as specified in DIN 13 Part 14. It may not be assumed that threaded rods for lengths of engagement greater than those specified for thread engagement group N as defined in DIN 13 Part 14 are true to gauge. Three standard types of threaded rods are manufactured, viz. property class 4.6.5.6 and 5.8 threaded rods. Other property classes or materials shall be subject to agreement.

Designation

Designation of an M10 threaded rod:

Threaded rod DIN 975 - M 10

Where a particular property class or other materials are required, the property class and the material shall be started in the designation, as for example:

Threaded rod DIN 975 - M 10 - 5.6

The DIN 4000-2-3 tabular layout of article characteristics shall apply to threaded rods conforming to this standard.
