The Carbon Steel Spring Clip Nut for Automobile Parts is a vital, yet often unseen, fastener securing components within vehicles. Its production demands precision to ensure consistent strength and reliable spring action under harsh conditions. The process begins with high-strength carbon steel strip, precisely sheared into blanks matching the clip nut's profile.
These blanks undergo progressive die stamping. Powerful presses rapidly punch the central nut body, form the initial clip shape, and pierce the mounting holes in a single, continuous operation. Next, critical bending stages form the clip's characteristic spring legs. Precise angles and radii are essential here to generate the necessary clamping force and allow deflection during installation onto panels or brackets.
Heat treatment follows to impart resilience. The formed clip nuts are hardened to achieve high tensile strength and then tempered (spring tempered) to restore crucial elasticity, enabling repeated flexing without fracturing. After thorough cleaning to remove oils and scale, the components receive a protective zinc plating. This coating, often applied via electroplating, provides essential corrosion resistance against road salts and moisture encountered in automotive environments.
Rigorous quality control permeates the process. Dimensions are meticulously verified using gauges and optical measurement. Spring tension and deflection are tested to ensure consistent holding power. Plating thickness and adhesion undergo strict checks. Finally, visual inspection eliminates any parts with burrs, cracks, or plating defects. Only components passing all checks are packaged for shipment, ready to perform their critical fastening role reliably within the automobile.
