Purpose-built for heavy-duty applications, this M11x143mm Hex Head Cap Screw features a nominal diameter of M11 and a precise length of 143mm, ensuring substantial engagement in threaded components. The 13mm hex head provides ample surface area for torque application with standard tooling. Manufactured from 304 stainless steel, it exhibits superior resistance to a broad spectrum of corrosive agents, including atmospheric conditions, acids, and alkaline solutions, making it ideal for marine, chemical processing, and outdoor structural assemblies where longevity and reliability are paramount. Its inherent tensile strength contributes to secure, load-bearing joints.
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 from debris. 2. Hand-thread the cap screw to verify proper alignment and prevent cross-threading. 3. Tighten using an appropriate wrench or socket to the recommended torque specification for the application, avoiding over-tightening.
