Fasteners are standardized metal connecting components manufactured through precision stamping, cold heading, turning, and heat treatment processes. Their core function is to securely connect two or more parts into a single unit, offering both detachability and structural stability.
Their core components (bolt heads, nut cavities, and washer surfaces) are largely formed using metal stamping processes, supporting both mass production of standard parts and custom manufacturing of non-standard parts.
They are widely used in all fields, including industrial manufacturing, construction engineering, electronics and electrical appliances, and agricultural machinery.
