Purpose-built for heavy-duty applications, this M7 x 145mm brass hex head cap screw boasts a nominal diameter of M7 and a length of 145mm, with a substantial 15mm hex head width for enhanced torque application. Manufactured from solid brass, it offers exceptional corrosion resistance, making it ideal for marine, chemical processing, and outdoor environments where rust and degradation are concerns. The material's inherent non-sparking properties also lend themselves to hazardous area installations. This fastener provides a secure and lasting mechanical connection, resisting galvanic corrosion when paired with compatible materials.
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 size for the 15mm hex head. 2. Carefully align the screw with the pre-drilled or tapped hole. 3. Apply consistent torque to seat the screw securely, avoiding over-tightening which can strip threads or damage components. 4. For critical applications, verify the torque specification with engineering drawings.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped hex heads. | Always use a properly sized wrench or socket that fits snugly on the hex head. |
| Over-tightening the screw, causing thread damage or component deformation. | Apply only the recommended torque. If unsure, consult engineering specifications or use a torque wrench. |
| Using brass screws in applications requiring high tensile strength or shear resistance beyond brass capabilities. | Verify the load requirements of the application and select a fastener material (e.g., steel alloys) that meets the necessary strength specifications. |
