Detailed Engineering Specifications

Built to exacting engineering tolerances, this M8x115mm hex head cap screw features a substantial 36mm head width for enhanced torque application and load distribution. Fabricated from Titanium Grade 5 (Ti-6Al-4V), it delivers a minimum tensile strength of 895 MPa and a yield strength of 828 MPa, while maintaining excellent biocompatibility and resistance to saltwater, chloride, and various chemical environments. The inherent lightweight nature of titanium (approximately 45% the density of steel) makes it ideal for weight-sensitive assemblies without compromising structural integrity. Its wide operating temperature range further expands its utility in demanding industrial and aerospace sectors.
