Built to exacting engineering tolerances, this M18 x 129mm hex head cap screw is manufactured from Titanium Grade 5 (Ti-6Al-4V), a widely recognized alloy for its excellent combination of high strength, low density, and outstanding corrosion resistance in aggressive media. The precise M18 thread pitch ensures reliable mating with standard components, while the 129mm length provides ample engagement for securing larger assemblies. The 9mm hex head offers a controlled torque application point. This fastener is ideal for aerospace, marine, chemical processing, and high-performance automotive applications where material integrity under stress and environmental duress is paramount.
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 of debris. 2. Apply appropriate thread locker if required by the application. 3. Tighten screw to the specified torque using a calibrated torque wrench, ensuring the head is seated flush.
