Trusted by engineers across multiple sectors, this M4x121mm Hex Head Cap Screw is precision manufactured from Titanium Grade 5 (Ti-6Al-4V). This aerospace-grade alloy provides a minimum tensile strength of 895 MPa and excellent fatigue resistance, making it ideal for applications where weight reduction and high load-bearing capacity are critical. Its inherent biocompatibility and non-magnetic properties further extend its utility. The M4 thread form ensures precise engagement, while the 121mm length and 33mm head width offer specific dimensional integrity for complex assemblies. The inherent corrosion resistance, particularly against saltwater and many chemicals, ensures long-term reliability in harsh conditions.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean mating surfaces and threads of both the screw and the receiving component to remove any debris or contaminants. 2. Apply a small amount of anti-seize compound to the threads, if specified by the application, to prevent galling. 3. Insert the screw and begin threading by hand to ensure proper alignment and prevent cross-threading. 4. Tighten the screw to the manufacturer's specified torque using a calibrated torque wrench, ensuring even pressure and avoiding over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening titanium fasteners can lead to thread stripping or head deformation due to the material's lower yield strength relative to its tensile strength compared to steel. | Always use a calibrated torque wrench and adhere to the manufacturer's recommended torque specifications for Grade 5 Titanium fasteners. |
| Failing to use anti-seize compound on titanium threads can result in galling, making removal difficult or impossible. | Apply a suitable anti-seize compound specifically designed for titanium to the screw threads before installation. |
