Purpose-built for heavy-duty applications, this M20 x 102mm hex head cap screw is fabricated from high-performance polycarbonate, renowned for its exceptional impact resistance, excellent tensile strength (approximately 60-80 MPa), and high dielectric strength. The M20 nominal diameter combined with a 102mm length and a 14mm across flats head width provides robust mechanical anchoring. Its inherent corrosion resistance makes it ideal for use in chemical processing, water treatment, marine, and outdoor installations where traditional metal fasteners would degrade. The operating temperature range typically extends from -40°C to 120°C, maintaining structural integrity under challenging conditions.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating threads are clean and free from debris. 2. Hand-thread the M20 polycarbonate cap screw into the receiving component until snug. 3. Apply torque using an appropriate metric hex wrench, ensuring even pressure. Do not overtighten, as polycarbonate can yield under excessive stress.
