Trusted by engineers across multiple sectors, this M8x31mm Hex Head Cap Screw is manufactured from Titanium Grade 5 (Ti-6Al-4V), renowned for its superior tensile strength, fatigue resistance, and biocompatibility, surpassing stainless steel in critical weight-sensitive and corrosive applications. With a nominal diameter of M8, a length of 31mm, and a precisely machined head width of 9mm, it ensures reliable and secure fastening in aerospace, medical implants, marine hardware, and high-performance automotive assemblies. Its inherent non-magnetic properties and low thermal expansion further enhance its suitability for specialized engineering challenges.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free from debris or damage. 2. Apply a suitable thread lubricant or anti-seize compound if recommended for the application. 3. Engage the screw by hand for at least two full turns to prevent cross-threading. 4. Tighten the screw to the specified torque using a calibrated torque wrench. Avoid over-tightening.
