A high-performance industrial component, this M18 x 89mm hex head cap screw is manufactured from 316 stainless steel, renowned for its exceptional resistance to pitting and crevice corrosion, particularly in saline and acidic environments. The M18 thread size denotes a nominal diameter of 18mm, with a length of 89mm from under the head to the thread tip. The substantial 24mm hex head width provides ample surface area for torque application, ensuring secure seating and preventing damage during assembly. This material composition makes it ideal for applications demanding long-term integrity and performance under stress, such as marine hardware, chemical processing equipment, and food processing machinery.
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. 2. Apply appropriate lubricant to threads if required by the application. 3. Tighten the cap screw to the specified torque using a calibrated torque wrench, engaging the hex head with a correctly sized socket.
