Purpose-built for heavy-duty applications, this M7x143mm Hex Head Cap Screw is manufactured from high-strength Nylon 6/6. The material offers excellent chemical resistance to a wide range of solvents, acids, and bases, making it ideal for corrosive environments. With a head width of 20mm, it provides ample bearing surface for secure fastening. The metric M7 thread size and 143mm length ensure compatibility with standard metric assemblies. Nylon's inherent dielectric properties also make it suitable for electrical insulation and preventing galvanic corrosion. Operating temperature range is -40°C to +100°C, with a tensile strength of approximately 70-100 MPa.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select appropriate torque wrench calibrated for nylon fasteners. 2. Engage the hex head with a compatible driver. 3. Tighten screw to the recommended torque for nylon, avoiding over-tightening to prevent material deformation or stripping. 4. Ensure the mating component is properly aligned to avoid cross-threading.
