DIN 977 Hex Weld Nuts

DIN 977 Nuts

DIN 977 standard nuts are hexagonal nuts with a flange, intended for welding. Welded Flange Nuts are made of steel. Coverage of such nuts with protective coating of non-ferrous metals is not allowed, as this may affect the reliability of the welded joint. They are welded using point or arc welding. Due to this, the fastening is securely fixed and the process of unauthorized unscrewing is minimized. as this may affect the reliability of the welded joint.
