Purpose-built for heavy-duty applications, this M4x64mm Hex Head Cap Screw is manufactured from Aluminum 6061, renowned for its excellent corrosion resistance, high tensile strength, and good weldability. The nominal diameter is M4, with a substantial 64mm length to accommodate thicker material joints. The 18mm hex head provides ample surface area for torque application, ensuring a secure and stable connection. This specification is ideal for applications requiring lightweight yet strong fasteners, commonly found in aerospace, automotive chassis, marine hardware, and structural components where weight reduction is a critical design parameter.
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 to the fastener's material and application requirements. 2. Ensure the mating threads are clean and free from debris or damage. 3. Insert the screw into the designated hole and tighten progressively until the desired torque is achieved, avoiding over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that is too small for the hex head, leading to stripping. | Utilize a properly sized wrench or socket that fully engages the 18mm hex head to prevent cam-out and damage. |
| Applying excessive torque beyond the yield strength of Aluminum 6061, causing deformation or failure. | Adhere to the recommended torque specifications for M4 Aluminum 6061 fasteners, as excessive force will compromise the integrity of the screw and mating components. |
