Designed for demanding industrial environments, this M12 x 87mm hex head cap screw is manufactured from high-performance polycarbonate. Its superior dielectric strength (typically 16-24 kV/mm) and excellent resistance to a broad spectrum of chemicals, including many acids, bases, and solvents, make it ideal for applications where metal fasteners would corrode or interfere with electrical signals. The generous head width of 33mm provides substantial bearing surface area, distributing load effectively and minimizing stress on mating materials. Operating temperature range for polycarbonate is typically -10°C to +120°C, offering robust performance across varied conditions.
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 cap screw into the receiving component to prevent cross-threading. 3. Tighten with an appropriate wrench to the recommended torque specification, avoiding overtightening to prevent material deformation.
