A proven choice for industrial professionals, this M18 x 89mm hex head cap screw is manufactured from Aluminum 6061, a widely recognized alloy for its excellent corrosion resistance, moderate strength, and good formability. The M18 designation signifies a nominal major diameter of 18mm, with a precisely controlled thread pitch. The 89mm length provides substantial engagement for secure fastening in a variety of joint configurations. The prominent 24mm hex head width allows for efficient and secure tightening with standard tooling, minimizing the risk of stripping. Aluminum 6061's inherent lightweight properties make this fastener ideal for applications where weight reduction is critical without compromising structural integrity.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating threads are clean and free of debris. 2. Insert the cap screw through the components to be joined. 3. Tighten the cap screw using an appropriately sized hex wrench or socket, applying torque according to design specifications. Avoid over-tightening.
