Manufactured under strict quality controls, this M18 x 85mm hex head cap screw is precision-engineered from premium 316 stainless steel. This grade provides superior corrosion resistance, especially in marine and chemical environments, due to its molybdenum content. The M18 thread standard ensures compatibility with standard metric nuts and tapped holes, while the 85mm length offers substantial grip for medium-duty applications. The 24mm hex head width is designed for standard metric wrench sizes, facilitating secure installation and removal. Its high tensile strength makes it suitable for applications requiring reliable load-bearing capacity.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate wrench or socket for the 24mm hex head. 2. Ensure mating threads are clean and free from debris. 3. Engage the screw and tighten to the required torque specification, avoiding over-tightening.
