Built to exacting engineering tolerances, this M12 x 70mm hex head cap screw is manufactured from high-performance polycarbonate. Its substantial 26mm head width ensures effective torque application, while the M12 thread size and 70mm length provide robust fastening capabilities. Polycarbonate's inherent dielectric properties, excellent impact resistance, and broad chemical inertness make this screw suitable for applications in electrical assemblies, medical equipment, and corrosive industrial settings where non-conductive and non-magnetic solutions are paramount. Its lightweight nature also contributes to reduced overall assembly weight.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate tool for the M12 hex head (e.g., socket wrench or hex key). 2. Align the screw with the pre-tapped hole or nut, ensuring threads engage smoothly. 3. Tighten the screw gradually to the required torque, avoiding over-tightening to prevent damage to the polycarbonate material.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to stripping of threads or cracking of the polycarbonate head. | Use a torque wrench to apply the specified torque for M12 fasteners, or tighten by hand until snug and then an additional quarter turn. |
| Using metal tools that can scratch or damage the polycarbonate surface. | Employ tools with plastic or rubber coatings, or exercise caution when using standard metal tools to prevent surface marring. |
