Specified by design engineers worldwide, this M18 x 34mm brass hex head cap screw features a robust M18 thread and a generous 34mm length, ensuring secure fastening in a wide range of applications. The substantial 31mm hex head width facilitates high torque application with standard tooling. Crafted from high-grade brass (commonly UNS C26000 or similar), it exhibits excellent resistance to corrosion, particularly in marine, humid, or chemically aggressive environments. Its non-ferrous nature also makes it suitable for electrical conductivity applications and where magnetic interference is a concern.
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 for the 31mm hex head. 2. Ensure the mating threaded hole is clean and free of debris. 3. Thread the cap screw by hand initially to prevent cross-threading, then tighten to the required torque specification using calibrated torque wrench.
