Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 18-8 stainless steel hex head screws combine material excellence with precision manufacturing. The UNC coarse thread pattern and Class 2A thread fit ensure rapid assembly in structural frameworks, machinery, and heavy equipment where vibration resistance is critical. The external hex drive provides maximum torque capability for high-clamp force requirements, while the fully threaded design maintains consistent holding power across the entire shank length. Ideal for industrial fastening in manufacturing plants, construction projects, and marine environments, these screws deliver reliable performance where corrosion resistance and mechanical strength are paramount.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with Class 2A thread fit tolerances for precision engagement. The 1/4"-20 UNC coarse thread configuration ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory adherence for global industrial applications.
