Designed for demanding industrial environments, this M18x86mm hex head cap screw boasts a 14mm head width and is constructed from high-performance polycarbonate. This advanced thermoplastic provides exceptional resistance to a wide array of chemicals, solvents, and corrosive agents, making it ideal for applications where metal fasteners would degrade. Its inherent dielectric properties eliminate electrical conductivity concerns, crucial for sensitive electronic enclosures and systems. The material's high impact strength ensures durability against mechanical stresses. Typical applications include chemical processing equipment, marine environments, medical device assembly, and food processing machinery where non-metallic, non-corrosive fastening is paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate threaded hole or nut with a matching M18 thread. 2. Insert the hex head cap screw, ensuring it engages smoothly with the threads. 3. Tighten the screw using a suitable hex driver until snug, avoiding overtightening to prevent material deformation.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the polycarbonate screw, leading to thread stripping or head deformation. | Use a torque wrench to apply the recommended torque for polycarbonate fasteners, or tighten until just snug. |
| Using a metal driver with sharp edges that can scratch or damage the polycarbonate head. | Employ a hex driver with smooth edges or a driver specifically designed for plastic fasteners. |
