Purpose-built for heavy-duty applications, this M20x47mm brass hex cap screw features a substantial M20 thread diameter and a 47mm length, providing deep engagement for secure connections. The 23mm head width allows for ample torque application using standard tooling. Crafted from high-grade brass, it exhibits exceptional resistance to corrosion, particularly in saline or chemically aggressive atmospheres, and possesses excellent electrical conductivity. This makes it an ideal choice for applications where galvanic corrosion is a concern or where non-magnetic and non-sparking characteristics are essential.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure threads on both the screw and the mating component are clean and free of debris. 2. Hand-thread the screw to confirm proper alignment and avoid cross-threading. 3. Using a calibrated wrench or socket, tighten the hex head to the recommended torque specification for the application, ensuring a secure fit without over-tightening.
