Trusted by engineers across multiple sectors, this M20 x 143mm hex head cap screw is manufactured from high-performance polycarbonate, renowned for its excellent chemical inertness, UV resistance, and non-conductive properties. With a nominal size of M20 and a total length of 143mm, it features a precisely machined 18mm hex head for secure torque application using standard tools. This material choice makes it ideal for applications in marine environments, chemical processing plants, and electrical assemblies where metal fasteners would corrode or pose a safety risk.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate mating component with a pre-tapped hole or a nut. 2. Hand-thread the polycarbonate hex head cap screw into the mating component to ensure proper alignment and prevent cross-threading. 3. Tighten the screw using a calibrated torque wrench set to the manufacturer's recommended torque value for M20 polycarbonate fasteners, applying even pressure.
