Built to exacting engineering tolerances, this M20 x 136mm hex cap screw is manufactured from high-performance polycarbonate. This advanced thermoplastic polymer exhibits excellent tensile strength, impact resistance, and broad chemical inertness, making it ideal for environments prone to corrosion or electrical conductivity concerns. With a nominal thread diameter of M20 and a head width of 23mm, it provides a secure and reliable fastening solution in applications requiring a substantial thread engagement and load distribution. Its lightweight nature also contributes to ease of handling and installation in sensitive assemblies.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threaded hole is clean and free of debris. 2. Hand-thread the screw into the receiving component to verify alignment and prevent cross-threading. 3. Tighten the screw using an appropriate wrench or socket, applying torque gradually until the desired clamping force is achieved, avoiding overtightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening leading to thread stripping or material fracture. | Apply torque gradually and adhere to recommended torque specifications for polycarbonate fasteners. Utilize a torque wrench for precise control. |
| Using the wrong tool size for the hex head, causing damage to the fastener. | Always use the correct size metric socket or wrench (23mm) for the hex head to ensure proper engagement and prevent cam-out or stripping. |
