Professional Applications & Engineering Value
These 316 stainless steel flat head screws are engineered to address critical challenges in demanding industrial settings, such as marine, chemical processing, and outdoor equipment. The passivated finish enhances the inherent corrosion resistance of 316 stainless steel, preventing failure in moist or chemically aggressive environments. The Class 3A UNC thread fit and coarse threading ensure rapid, secure assembly with minimal risk of cross-threading, reducing installation errors and maintenance downtime. The 82° countersink angle allows the screw to sit flush with surfaces, essential for applications requiring aerodynamic profiles or smooth finishes. Combined with a 5/64" hex drive, these screws offer reliable fastening in high-vibration applications, making them ideal for machinery, enclosures, and structural assemblies where durability and precision are paramount.
Specification Summary & Compliance
This screw features a 6-32 UNC thread with a Class 3A thread fit for precise dimensional accuracy and secure fastening. Manufacturing and dimensional specifications strictly adhere to ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various industrial and commercial applications.
