DIN 6331/6923/977 Flange Nuts

The DIN 6331/6923/977 flange nuts and the general hexagon nut are basically the same in size and thread specification, but compared with the hexagon nut, the gasket and the DIN 6331/6923/977 flange nuts are integrated, and there are anti-skid tooth patterns on the bottom, which increases the nut and the workpiece. Compared with the combination of ordinary nut and washer, it is firmer and has greater tensile force. The flange nut surface itself has the anti-slip and stop functions of the flat washer and the spring washer, so there is no need to add the flat washer and the spring washer during assembly, which will be counterproductive.
