A high-performance industrial component, this M4 x 119mm carbon steel hex head cap screw is engineered for exceptional load-bearing capacity and durability. The material composition, typically SAE 1018 or similar, provides a good balance of tensile strength and ductility, making it suitable for dynamic stress environments. With a nominal diameter of M4 and an overall length of 119mm, it offers significant engagement in threaded applications. The prominent 12mm hex head ensures secure and positive torque application with standard tooling, facilitating efficient assembly and disassembly processes in manufacturing, machinery, and structural frameworks.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate tool (e.g., socket wrench) with a 12mm drive size. 2. Insert the cap screw into the pre-drilled and tapped hole or through-hole with a mating nut. 3. Apply torque evenly until the desired clamping force is achieved, ensuring the fastener is seated flush against the mating surface.
