Engineered for reliability and performance, this M18 x 122mm hex head cap screw is manufactured from high-grade brass (e.g., UNS C36000 free-machining brass), offering excellent machinability and inherent corrosion resistance, particularly against water and certain chemicals. The hexagonal head, measuring 23mm across flats, provides a robust surface for torque application using standard wrenches. Its nominal diameter of M18 and a substantial length of 122mm make it suitable for joining thicker materials or bridging larger gaps in applications demanding both strength and resistance to environmental degradation. The material's non-sparking and non-magnetic characteristics are critical in sensitive environments.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select appropriate tooling, ensuring wrench size matches the 23mm hex head. 2. Insert screw into aligned pre-drilled holes. 3. Tighten screw to the required torque specification for the application, ensuring even pressure.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force which can strip threads or damage the brass material. | Consult engineering drawings or torque charts for the appropriate tightening specification and use a calibrated torque wrench. |
| Using incompatible mating hardware (e.g., steel nuts/washers) in corrosive environments, leading to galvanic corrosion. | Ensure all mating hardware is also made of brass or a compatible corrosion-resistant material to maintain the integrity of the joint. |
