Purpose-built for heavy-duty applications, this M20 x 12mm Hex Head Cap Screw leverages the inherent strength and impact resilience of polycarbonate. With a nominal diameter of M20 and a short length of 12mm, its substantial 34mm head width distributes load effectively, minimizing stress on mating components. Polycarbonate offers excellent resistance to a broad spectrum of chemicals, solvents, and oils, making it ideal for corrosive or sterile environments. Its non-conductive properties and UV stability further enhance its utility in diverse industrial settings, including food processing, medical equipment, and chemical handling systems.
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 of debris. 2. Hand-thread the screw to engage initial threads, verifying alignment. 3. Torque the screw to the manufacturer's recommended specification for polycarbonate fasteners, avoiding over-tightening.
