Trusted by engineers across multiple sectors, this M19x149mm brass hex head cap screw offers excellent resistance to corrosion, particularly in marine and chemical-exposed applications. Composed of a durable brass alloy, it provides sufficient tensile strength for general-purpose structural joining where non-ferrous properties are critical. The M19 nominal diameter and 149mm length, coupled with a 12mm head width, ensure compatibility with standard tooling and pre-tapped or through-hole assemblies, making it a dependable choice for electrical grounding, plumbing, and decorative fixtures.
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. Engage the threads by hand initially to prevent cross-threading. 4. Tighten the cap screw using an appropriate wrench or socket, applying the recommended torque for brass fasteners.
