Request a quote Applications and selection Threaded rods (DIN 975, DIN 976) are used for suspending services – ventilation ducts, cable trays and pipework – and as tie rods and structural connectors. They are cut to length and fitted with nuts; coupling nuts are used to extend them. For chemical anchoring, the rod must meet the requirements of the anchoring system used. Retaining rings (DIN 471, DIN 472) locate parts such as bearings and gears on a shaft or in a bore, and are selected by shaft or bore diameter and groove dimensions. E-type retaining rings (DIN 6799) are fitted radially into a shaft groove. Spring pins (DIN 1481) are press-fitted – their nominal diameter matches the hole diameter. Frequently asked questions What is the difference between DIN 975 and DIN 976 threaded rods? DIN 975 covers threaded rods in commercial lengths, while DIN 976 covers threaded rods and studs in various lengths. In practice both designations are used for fully threaded rods. How do I choose a retaining ring? Select the ring by shaft diameter (DIN 471) or bore diameter (DIN 472) and the groove dimensions. Suitable circlip pliers are used for fitting. Can threaded rod be used for chemical anchoring? Yes, provided it meets the requirements of the anchoring system, e.g. property class, material and length. The anchor manufacturer’s documentation and the design are decisive. What information should an enquiry include? Standard, size (diameter, length), material or coating and quantity.
