Engineered for reliability and performance, this M20 x 82mm hex head cap screw features a nominal diameter of 20mm and a thread pitch of 2.5mm (coarse thread). The head exhibits a nominal width of 28mm, providing ample surface area for torque application. Manufactured from Aluminum 6061, a precipitation-hardening aluminum alloy, it offers excellent mechanical properties including good tensile strength, yield strength, and fatigue resistance, coupled with superior corrosion resistance. This combination makes it suitable for applications requiring a lightweight yet durable fastening solution, particularly in marine, aerospace, and automotive sectors where weight reduction and environmental resilience are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free from debris. 2. Hand-thread the screw to verify alignment and prevent cross-threading. 3. Tighten the screw to the specified torque value using an appropriate wrench, ensuring the head is seated flush.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the aluminum screw, leading to thread stripping or deformation. | Utilize a torque wrench set to the manufacturer's recommended torque specification for Aluminum 6061 fasteners of this size. |
| Using the wrong tool size for the hex head, resulting in cam-out and potential damage to the head. | Employ a properly sized hex socket or wrench that fits snugly to ensure maximum engagement and prevent slippage. |
