Professional Applications & Engineering Value

These 3/8"-16 UNC flat head screws are engineered to address critical fastening challenges in industrial settings, such as machinery assembly, structural frameworks, and equipment manufacturing. The zinc-plated steel material provides a protective barrier against moisture and chemicals, extending service life in harsh conditions. With coarse thread spacing and Class 2A thread fit, they ensure quick, secure installation without compromising alignment, reducing the risk of strip-out in high-vibration environments. The fully threaded design maximizes grip along the entire 1" length, distributing stress evenly to prevent joint failure. Ideal for applications requiring flush surface finishes and reliable tensile strength, these screws deliver consistent performance while meeting stringent ASME B18.6.3 specifications for dimensional accuracy and safety.

Specification Summary & Compliance

This product adheres to Class 2A thread fit tolerances and UNC coarse thread standards, ensuring precise dimensional accuracy per ASME B18.6.3. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. Manufactured with a standard 82° countersink angle and right-hand thread direction, it meets industry benchmarks for reliability and safety in inch-system applications.
