A high-performance industrial component, this M21x86mm Hex Head Cap Screw is manufactured from Titanium Grade 5 (Ti-6Al-4V), renowned for its outstanding tensile strength, fatigue resistance, and biocompatibility. With a nominal diameter of M21 and a precise length of 86mm, it features a robust 15mm hex head for secure torque application. Its exceptional corrosion resistance in saline, acidic, and alkaline environments makes it the fastener of choice for aerospace, medical implants, marine, and chemical processing industries where failure is not an option.
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 from debris. 2. Apply appropriate anti-seize compound if specified for the application. 3. Thread the screw into the mating component by hand to ensure proper alignment and prevent cross-threading. 4. Tighten the screw to the manufacturer's specified torque value using a calibrated torque wrench, engaging the 15mm hex head.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing the titanium screw, leading to thread stripping or component damage. | Always use a calibrated torque wrench and adhere to the specified torque values for Titanium Grade 5 fasteners, considering the mating material's properties. |
| Using standard steel tools that can gall or damage the titanium head. | Employ high-quality, properly sized tools made from hardened steel or specialized alloys to avoid galling and ensure a secure grip on the hex head. |
| Not using an anti-seize compound when recommended, potentially leading to galling or seizing, especially in dissimilar metal applications. | Consult application guidelines and use a suitable anti-seize compound specifically designed for titanium fasteners to prevent galling and facilitate disassembly. |
