Specified by design engineers worldwide, this M18 x 89mm Hex Head Cap Screw leverages the superior properties of Titanium Grade 5 (Ti-6Al-4V). This alloy exhibits an excellent combination of high tensile strength (up to 900 MPa), fatigue strength, and outstanding corrosion resistance, making it ideal for environments exposed to aggressive chemicals, saltwater, and high temperatures. The M18 thread provides robust load-bearing capacity, while the 89mm length ensures sufficient engagement in various joint configurations. The 36mm hex head width is designed for standard tooling, allowing for controlled torque application in demanding applications.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating threads are clean and free from debris. Apply a suitable anti-seize compound if specified by design parameters. 2. Align the screw with the threaded hole or nut, ensuring a smooth start without cross-threading. 3. Tighten the screw to the specified torque value using a calibrated torque wrench, applying force evenly across the hex head.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the titanium screw, exceeding its yield strength or damaging the mating threads. | Always use a calibrated torque wrench and adhere to the torque specifications provided by the design engineer or relevant standards. |
| Using incorrect tools, which can strip the hex head or lead to uneven torque application. | Utilize properly sized, high-quality hex sockets or wrenches designed for the specified head width. |
