Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel rounded head screws deliver critical corrosion resistance where exposure to chemicals, moisture, or extreme temperatures would compromise ordinary fasteners. The UNC coarse thread configuration combined with Class 3A precision tolerance ensures rapid installation and reliable performance in high-vibration applications across machinery, marine equipment, and chemical processing systems. The flanged button head design provides superior bearing surface while the fully threaded construction maintains consistent clamping force. With hex drive compatibility and passivated finish, these screws withstand rigorous installation torque while maintaining their protective properties, making them ideal for maintenance-critical applications where disassembly and reassembly are frequent.
Specification Summary & Compliance
This 10-24 UNC threaded screw features Class 3A thread fit per ASME B1.1 standards, ensuring precision tolerance for secure fastening. The 1 1/2" length with fully threaded design provides consistent engagement depth. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and material safety for global industrial applications.
