Precision-manufactured to tight tolerances, this M4 x 147mm hex head cap screw features a substantial 29mm head width for effective torque application and load distribution. Constructed from high-impact polycarbonate, it exhibits excellent tensile strength, impact resistance, and superior corrosion resistance compared to metallic fasteners. The inherent dielectric properties of polycarbonate make it suitable for electrically sensitive applications, preventing short circuits or galvanic corrosion. This screw is engineered for environments where weight reduction, non-conductivity, and resistance to aggressive chemicals are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select appropriate tooling (e.g., hex wrench or socket) matching the M4 thread and 29mm head width. 2. Insert the screw into the pre-drilled or tapped hole, ensuring smooth engagement of threads. 3. Tighten the screw to the required torque specification, avoiding over-tightening which could damage the polycarbonate material.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during tightening, leading to material cracking or stripping of threads. | Adhere to recommended torque values for polycarbonate fasteners and use appropriate tooling to prevent over-tightening. |
| Exposure to extreme temperatures beyond the operational limits of polycarbonate, causing degradation or deformation. | Verify the operating temperature range of polycarbonate and ensure the application falls within these parameters. |
