Purpose-built for heavy-duty applications, this M17x78mm brass hex head cap screw features a substantial M17 thread diameter and a 78mm length, providing deep engagement for secure fastening. The 24mm hex head width ensures ample surface area for torque application with standard tools. Crafted from high-grade brass, it exhibits exceptional resistance to corrosion and tarnishing, making it ideal for environments exposed to moisture, chemicals, or saltwater. The material's inherent non-sparking properties also lend themselves to hazardous area applications.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating threads are clean and free of debris. 2. Hand-thread the screw into the receiving component to verify alignment and prevent cross-threading. 3. Use an appropriately sized wrench or socket to tighten the hex head to the desired torque specification, ensuring a secure fit without over-tightening.
