Professional Applications & Engineering Value
These 400 Nickel hex head screws deliver critical performance advantages in demanding applications where corrosion resistance and mechanical strength are paramount. The combination of 80,000 psi tensile strength and Rockwell B80 hardness makes them ideal for heavy machinery, marine equipment, and chemical processing installations where standard fasteners would fail. The UNC coarse threading provides superior holding power in soft materials and prevents cross-threading during assembly. With full threading along the entire 3/4" length, these screws offer maximum engagement depth and adjustability. The external hex drive accommodates high torque requirements while the Class 2A thread fit ensures consistent performance across production runs, reducing assembly time and improving manufacturing efficiency.
Specification Summary & Compliance
This 1/4"-20 UNC hex head screw features precision Class 2A thread fit tolerances and coarse thread spacing for reliable performance. Manufactured to meet ASTM F468 and MIL-S-1222 specifications, ensuring consistent quality and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material restrictions adherence for global industrial applications.
