32980001ZXM8 – LITTELFUSE

The LITTELFUSE 32980001ZXM8 is a zinc-plated steel bolt specifically designed for securing ZCASE high-current fuses in automotive starter applications. This M8 bolt conforms to metric standard M8x1.25, indicating a nominal diameter of 8mm and a thread pitch of 1.25mm. The zinc plating provides corrosion resistance, essential for under-hood environments. Its primary function is to ensure a reliable and low-resistance electrical connection between the ZCASE fuse and the associated busbar or terminal. The bolt’s head geometry is optimized for accessibility and torque application, facilitating proper tightening to the manufacturer’s specified torque value to maintain consistent contact pressure and prevent loosening due to vibration. The material composition and plating thickness are selected to withstand typical automotive operating temperatures and humidity levels, ensuring long-term electrical performance and mechanical integrity of the fuse connection.
