Precision-manufactured to tight tolerances, this M13x28mm Hex Head Cap Screw features a 34mm head width, ensuring broad load distribution. Composed of high-performance polycarbonate, it exhibits excellent tensile strength (typically 70-80 MPa) and a low coefficient of friction. Its inherent dielectric strength (up to 20 kV/mm) and resistance to a wide range of chemicals, including acids and alkalis, make it a superior choice for corrosive environments and electrical assemblies. The material's lightweight nature (specific gravity ~1.2) contributes to reduced overall assembly weight, while its operating temperature range (-40°C to +120°C) ensures performance across diverse industrial settings.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free from debris. 2. Manually thread the M13x28mm polycarbonate cap screw into the receptacle until snug. 3. Tighten using an appropriate hex wrench, applying torque gradually to avoid overstressing the polycarbonate material. Refer to torque charts for specific applications.
