A high-performance industrial component, this M4x22mm Hex Head Cap Screw is manufactured from high-impact polycarbonate, offering superior strength-to-weight ratio and excellent resistance to chemicals and corrosion. The material's inherent dielectric properties make it ideal for applications requiring electrical isolation. The precise M4 thread pitch and 22mm length ensure secure fastening, while the expansive 24mm hex head width provides exceptional surface area for torque application and load bearing, preventing damage to mating materials. This design is optimized for environments where both mechanical integrity and electrical safety are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean and free of debris. 2. Align the screw with the pre-drilled or tapped hole. 3. Hand-tighten the screw initially to engage threads, then use an appropriate hex driver to achieve desired torque. Avoid overtightening to prevent material deformation.
