Precision-manufactured to tight tolerances, this M5x123mm Hex Head Cap Screw is fabricated from Aluminum 6061, a precipitation-hardened alloy renowned for its excellent strength-to-weight ratio, good corrosion resistance, and weldability. The M5 thread conforms to ISO standards, ensuring compatibility with standard M5 nuts and tapped holes. With a nominal head width of 18mm, this provides ample surface area for torque application via a standard M5 hex key or wrench, facilitating secure fastening. The 123mm length allows for deep engagement in thicker materials or for spanning larger gaps in structural assemblies. Ideal for environments where weight reduction is paramount and galvanic corrosion is a concern.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate torque wrench calibrated for M5 fasteners. 2. Ensure mating threads are clean and free of debris. 3. Thread the cap screw into the receiving component, applying even pressure, until snug. 4. Torque the screw to the manufacturer's specified value for Aluminum 6061, typically between 2-4 Nm for an M5 thread, to avoid overstressing the material or threads.
