Selection for the joint
For hot-dip galvanising, select a compatible nut and bolt thread fit system. Diameter M12 and pitch 1,75 mm alone do not confirm compatibility. Check the designations and documentation of the specific batch. Oversized nuts marked Z or X must not be combined with undersized bolts marked U.
The stated dimensions m and s and product grade A refer to catalogue dimensions before coating application. They are not measurements of a finished galvanised piece. No separate thread tolerance class after galvanising is confirmed for this specific offer; 6H, 6AZ or 6AX has not been assigned automatically.
The standards are given as catalogue references. They do not confirm full DIN 934 and ISO 4032 interchangeability or constitute a test result for the specific batch. Coating thickness, steel grade, tightening torque or operating temperature are not specified without confirmation for this offer.
