Manufactured under strict quality controls, this M18x70mm Hex Head Cap Screw is constructed from premium Titanium Grade 5 (Ti-6Al-4V), ensuring a minimum tensile strength of 895 MPa and excellent biocompatibility. The M18 thread pitch and 70mm length provide robust joining capabilities, while the 23mm hex head offers a substantial bearing surface for secure torque application. Its inherent lightweight nature and resistance to galvanic corrosion make it indispensable in aerospace, medical implants, marine, and chemical processing industries where performance and longevity are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure threads on both the screw and mating component are clean and free of debris. 2. Apply a small amount of anti-seize lubricant to the threads to prevent galling, especially in titanium-to-titanium applications. 3. Engage the screw by hand to verify thread alignment before applying torque. 4. Tighten using a calibrated torque wrench to the manufacturer's specified torque value, ensuring even pressure and avoiding over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force or overtightening, leading to thread stripping or galling, particularly common with titanium. | Always adhere to recommended torque specifications and use a calibrated torque wrench. Employ anti-seize compounds specifically designed for titanium. |
| Cross-threading the screw, which damages both the screw and the mating component's threads. | Carefully align the screw with the receiving threads and start insertion by hand to confirm proper engagement before using a tool. |
