Professional Applications & Engineering Value
These 4-40 UNC hex head screws deliver critical performance where corrosion resistance and high tensile strength are paramount. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making them ideal for marine, food processing, and outdoor equipment applications. The coarse UNC threading and Class 2A thread fit ensure rapid assembly while minimizing the risk of cross-threading in production environments. The fully threaded design along the complete 1" length distributes clamping force evenly, preventing joint loosening from vibration. With 80,000 PSI tensile strength and Rockwell B70 hardness, these external hex drive screws maintain their mechanical properties through demanding cycles, reducing maintenance frequency and downtime in industrial settings.
Specification Summary & Compliance
This 4-40 UNC hex head screw features precise Class 2A thread fit with right-hand coarse threading, manufactured to standard inch system dimensions. The fastener maintains 0.112" thread diameter with 1" full threading length and 3/16" hex head width for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while meeting standard mechanical requirements for stainless steel fasteners.
