Specified by design engineers worldwide, this M13 x 87mm hex cap screw is manufactured from high-grade brass, renowned for its excellent corrosion resistance, moderate strength, and non-magnetic properties. The 25mm hex head width ensures positive engagement with standard wrenches, facilitating secure installation and removal. Its ductility makes it suitable for applications requiring some deformation without fracture. This fastener is commonly employed in environments prone to moisture and corrosive elements, such as marine hardware, electrical connectors, and decorative fixtures where both performance and appearance are critical.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the threaded hole is clean and free from debris. 2. Align the screw with the corresponding tapped hole or nut. 3. Engage the hex head with an appropriate wrench or socket. 4. Tighten the screw to the required torque, avoiding over-tightening which can strip threads or damage the material.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during tightening. | Apply torque gradually and use a torque wrench to adhere to specified torque values for the material and application. |
| Cross-threading the screw during installation. | Carefully start threading the screw by hand to ensure proper alignment before applying any tool. |
| Using brass screws in high-stress structural applications. | While brass offers good corrosion resistance, it has lower tensile strength than steel. Evaluate load requirements and consider steel alloys for critical structural joints. |
