Specified by design engineers worldwide, this M20 x 16mm hex head cap screw is manufactured from high-performance polycarbonate, renowned for its superior impact strength, excellent electrical insulation properties, and broad chemical resistance. The M20 thread size ensures robust fastening, while the 16mm length offers versatile application. The 30mm head width provides ample bearing surface for secure tightening. Its transparent or colored options make it suitable for aesthetic and functional integration in various assembly processes, particularly where metal fasteners are undesirable due to corrosion, conductivity, or weight concerns.
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 an M20 tapped hole or nut. 2. Insert the M20 x 16mm polycarbonate hex head cap screw through the components to be joined. 3. Hand-tighten the screw initially to ensure proper thread engagement and alignment. 4. Using a suitable wrench or socket of the appropriate size for the 30mm head width, tighten the screw to the required torque specification, avoiding over-tightening which could damage the polycarbonate.
