Manufactured under strict quality controls, this M4 x 100mm hex head cap screw offers a nominal diameter of M4 and a thread length of 100mm. Constructed from 316 stainless steel, it exhibits excellent resistance to pitting and crevice corrosion in chloride-rich environments, making it suitable for marine, chemical processing, and food service applications. The hex head, with a nominal width of 22mm, allows for high torque application using standard hex wrenches or sockets. Its tensile strength and fatigue resistance ensure reliable performance in structural and mechanical assemblies.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate torque wrench or driver for the M4 thread size. 2. Ensure the mating threads are clean and free from debris. 3. Thread the cap screw into the receiving component, applying consistent, controlled torque to the specified value for the application, avoiding over-tightening.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard steel screw in a corrosive environment. | Always specify 316 stainless steel for applications exposed to saltwater, chemicals, or high humidity to prevent premature corrosion and component failure. |
| Over-tightening the screw, leading to thread stripping or material fatigue. | Utilize a calibrated torque wrench and adhere to the recommended torque specifications for the M4 thread size and the materials being joined. |
