Professional Applications & Engineering Value
This 3/8"-16 UNC pentagon head screw delivers critical engineering advantages where standard fasteners fail. The 18-8 stainless steel composition provides inherent corrosion resistance that extends service life in chemical processing, marine, and outdoor installations. The external pentagon drive system offers superior torque transmission compared to conventional drives, preventing tool slippage and reducing installation damage. With coarse thread spacing and Class 2A thread fit, these screws excel in vibration-prone machinery, structural steel connections, and heavy equipment assembly where loosening prevention is paramount. The combination of 70,000 PSI tensile strength and Rockwell B70 hardness ensures reliable performance in high-stress industrial applications while maintaining reusability.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent engagement. Features UNC coarse thread specification (3/8"-16) with right-hand threading direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fully threaded design maintains uniform stress distribution across the entire 3/4" length, while the 13/16" external pentagon drive ensures optimal torque application in industrial fastening systems.
