Manufactured under strict quality controls, these M20 x 82mm hex head cap screws are crafted from premium brass, offering excellent ductility, machinability, and inherent corrosion resistance, particularly against saltwater and certain chemicals. The M20 nominal diameter provides substantial load-bearing capacity, with a fully threaded shaft extending to 82mm. The 25mm hex head facilitates secure tightening with standard tooling, ensuring consistent torque application and preventing over-stressing of the material. This brass alloy is non-magnetic and possesses good electrical conductivity, making it suitable for specialized applications.
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 (25mm). 2. Ensure the mating threads are clean and free of debris. 3. Insert the screw into the pre-tapped hole or through the clamped components. 4. Tighten the screw to the required torque specification, avoiding over-tightening to prevent thread stripping or material deformation.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect tool size, leading to cam-out and damage to the hex head. | Always use a properly sized 25mm hex socket or wrench to ensure full engagement and prevent damage. |
| Applying excessive torque, potentially stripping threads or deforming the brass. | Adhere to manufacturer-recommended torque values or use a calibrated torque wrench. Brass is softer than steel and requires careful torque management. |
| Using brass screws in applications requiring high tensile strength or significant shear loads. | Evaluate the load requirements of your application. While brass offers good strength, it may not be suitable for heavy structural or high-stress fastening needs. Consider steel or stainless steel alternatives if necessary. |
