A high-performance industrial component, this M5 Hex Head Cap Screw boasts a nominal diameter of 5mm and a substantial 129mm length. The head features a 14mm hex width for reliable torque application with standard tooling. Constructed from high-impact, chemically resistant polycarbonate, it offers excellent dielectric strength and a wide operating temperature range. Its inherent non-magnetic and non-corrosive nature makes it suitable for environments where metal fasteners would degrade or interfere with sensitive equipment, such as medical devices, food processing machinery, and electronic enclosures.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate M5 threaded hole and ensure it is clean and free from debris. 2. Insert the Hex Head Cap Screw, ensuring it engages smoothly with the threads. 3. Tighten the screw using a 14mm hex wrench or socket, applying torque incrementally to achieve secure fastening without over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening polycarbonate screws, which can lead to cracking or stripping of the threads. | Apply firm but controlled torque, utilizing a torque wrench if precise specifications are required. Avoid excessive force. |
| Using metal tools that could scratch or damage the polycarbonate surface. | Employ tools with soft tips or ensure that metal tools do not come into direct contact with the screw head or shaft during installation. |
