Trusted by engineers across multiple sectors, this M13 x 135mm Hex Head Cap Screw is manufactured from high-grade Aluminum 6061, renowned for its excellent corrosion resistance and moderate to high strength. The alloy's composition (approximately 96-97% aluminum, with magnesium and silicon) provides a good balance of mechanical properties and formability. The M13 thread size and 135mm length, coupled with a 30mm head width, are engineered for secure torque application and load distribution in applications requiring lightweight yet durable fastening solutions. Typical applications include marine hardware, aerospace components, automotive assemblies, and structural frameworks where weight reduction is critical.
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 screw, hand-tightening to avoid cross-threading. 3. Tighten to the specified torque value using an appropriate wrench, ensuring even pressure distribution.
