Designed for demanding industrial environments, this M23 x 138mm brass hex head cap screw provides reliable and long-lasting fastening solutions. Constructed from high-grade brass, it exhibits exceptional corrosion resistance, making it ideal for marine, chemical processing, and food and beverage applications where standard steel fasteners would degrade. Its non-sparking properties are critical for use in potentially explosive atmospheres. The nominal size is M23, with a thread pitch of 3.0mm (coarse). The overall length is 138mm, and the hex head provides a secure grip for torque application, with a head width of 13mm across flats. The material's inherent malleability allows for conforming fits, while its tensile strength is sufficient for many structural and mechanical joining tasks.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating threads are clean and free from debris. 2. Engage the hex head cap screw with the corresponding tapped hole or nut. 3. Apply torque evenly using an appropriate wrench or socket until the desired clamping force is achieved, avoiding over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using brass screws in applications requiring high tensile strength or shear strength. | Evaluate the load requirements carefully and select fasteners with appropriate material properties (e.g., steel alloys) for critical structural applications. |
| Applying excessive torque, leading to thread stripping or material deformation. | Adhere to recommended torque specifications for the fastener size and material, and utilize a torque wrench for precise application. |
