DIN 928 square nut, welded. The use of such metal products makes it possible not only to connect, but also to bond thin metal surfaces by welding. For this purpose, the welded nut has protrusions on four sides and is uncoated for better grip. The fastener is used most often in agricultural machinery with high vibration loads.
The steel used for welded nuts is carbon steel with a strength class of 4.8, as well as stainless steel A2-70, which will ensure reliable operation in shipbuilding and other industries where there are conditions for high humidity. The welded nut DIN 928 is welded using condenser spot or arc welding.
