Comparison and Introduction of Cold Heading and Hot Heading Nuts for Fasteners

Comparison and Introduction of Cold Heading and Hot Heading Nuts for Fasteners

Cold heading is the use of the plasticity of metals, using cold mechanics to apply pressure or cold drawing, to achieve the goal of solid deformation of metals. On the surface, cold heading products look more beautiful and have better smoothness than hot heading products. In terms of use, hot heading nuts generally have higher hardness and strength than cold heading products. For users with high requirements, there are significant differences in materials.
