Detailed Engineering Specifications

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.
