Detailed Engineering Specifications

A high-performance industrial component, this M16 x 105mm hex head cap screw is manufactured from high-grade polycarbonate. Its robust material composition ensures excellent resistance to a wide range of chemicals, including acids, alkalis, and solvents, preventing degradation and maintaining structural integrity. The inherent non-conductive nature of polycarbonate makes it an ideal choice for applications requiring electrical isolation, mitigating risks of short circuits or galvanic corrosion. With a nominal diameter of M16, a length of 105mm, and a head width of 26mm, it offers substantial fastening capacity while maintaining a low profile. This makes it suitable for use in environments where corrosion or electrical conductivity are critical concerns, such as chemical processing plants, marine applications, and electronic assembly.
