A high-performance industrial component, this M4x104mm hex head cap screw is manufactured from solid brass, offering exceptional corrosion resistance, particularly in marine, chemical, and high-humidity settings. The nominal diameter is M4, with a total length of 104mm, and a generous head width of 32mm, facilitating secure and stable assembly. Brass's non-magnetic properties and good electrical conductivity make it suitable for sensitive electronic and electrical applications where ferrous materials are undesirable. Its inherent malleability allows for effective sealing in certain joint designs.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free from debris. 2. Align the cap screw with the pre-drilled or tapped hole. 3. Apply appropriate torque using a suitable wrench on the hex head until the desired clamping force is achieved. Avoid overtightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force, leading to thread stripping or component damage. | Refer to material strength charts or conduct load testing to determine the appropriate torque specification for the application. |
| Incorrect thread engagement, resulting in a weak or unreliable connection. | Verify that the screw threads fully engage with the mating threads for at least 1.5 to 2 times the screw's nominal diameter. |
