Professional Applications & Engineering Value
These 400 Nickel Socket Head Cap Screws with 4-40 UNC coarse threading and Class 3A fit are engineered to address common challenges in corrosive and high-stress environments. The 400 Nickel material offers exceptional resistance to oxidation and chemical exposure, making these fasteners a reliable alternative to Monel in applications like marine equipment, chemical processing, and aerospace components. The socket head design with a 3/32" hex drive ensures secure tool engagement, minimizing slippage and allowing for precise torque application in tight spaces. With a tensile strength of 70,000 psi and Rockwell B60 hardness, they maintain structural integrity under dynamic loads, reducing the risk of fastener failure and maintenance downtime in demanding industrial settings.
Specification Summary & Compliance
This product features a 4-40 UNC coarse thread with Class 3A precision fit, ensuring consistent thread engagement and dimensional accuracy. The screws are fully threaded with a right-hand direction and comply with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) regulations, supporting environmentally responsible manufacturing practices.
