Designed for demanding industrial environments, this M4 x 84mm hex head cap screw is manufactured from high-grade carbon steel, providing superior tensile strength and resistance to shear forces. The 20mm head width ensures adequate surface contact for secure tightening with standard hex tools. Its precise threading (M4) and length (84mm) are optimized for applications requiring extended reach and reliable load-bearing capacity in machinery, structural assemblies, and fabrication projects where material integrity is paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate wrench or socket for the M4 hex head. 2. Thread the cap screw into the pre-tapped hole or through the mating components. 3. Tighten the screw to the recommended torque specification for the material and application, ensuring a secure fit without over-stressing the components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a metric screw in an imperial threaded hole, or vice versa. | Always verify thread pitch and diameter compatibility (M4 metric) before installation. |
| Over-tightening the screw, leading to thread stripping or component damage. | Employ a torque wrench and consult application-specific torque charts for the correct tightening force. |
