Hexagon nuts DIN 936-1985 are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts. Connect (in the nut, M4 refers to Hexagon nuts DIN 936-1985 with an inner diameter of about 4mm, 0.7 refers to the distance between the two threads of 0.7mm); the nut is a nut, which is screwed together with a bolt or screw for lifting Fastening parts, a component that must be used in all manufacturing machinery, are classified into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials.
