A proven choice for industrial professionals, this M20 x 21mm Hex Head Cap Screw features a robust design with a 36mm head width for secure torque application. Manufactured from Titanium Grade 5 (Ti-6Al-4V), it exhibits an impressive tensile strength of 950 MPa and excellent fatigue life, making it ideal for environments prone to saltwater, chemicals, and high temperatures. Its inherent biocompatibility and non-magnetic properties also lend themselves to specialized uses in medical and electronic sectors. This fastener meets stringent industry standards for reliability and durability in demanding operational conditions.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean both the threaded hole and the screw threads to remove any debris or contaminants. 2. Apply a small amount of anti-seize lubricant to the threads, especially if dissimilar metals are involved or in corrosive environments. 3. Hand-tighten the screw to engage the threads, then use an appropriate torque wrench set to the manufacturer's specified torque value for M20 Grade 5 titanium fasteners to secure the joint.
