Professional Applications & Engineering Value
Engineered for critical industrial applications, this 3/8"-16 UNC hex head screw combines 18-8 stainless steel material with ASTM A193 Grade B8 certification to solve common engineering challenges in chemical processing, power generation, and marine equipment. The coarse UNC thread profile with partial threading prevents thread stripping in soft materials while maintaining vibration resistance. With 75,000 PSI tensile strength and Rockwell B100 hardness, it withstands extreme mechanical stresses and corrosive environments where standard fasteners fail. The external hex drive ensures positive torque transmission during installation, making it ideal for high-pressure piping systems, structural frameworks, and heavy machinery assemblies requiring reliable, maintenance-free performance.
Specification Summary & Compliance
This hex head screw features precision Class 2A thread fit with UNC coarse threads and right-hand thread direction. Manufacturing complies with ASTM A193 Grade B8 specifications for high-temperature service. The fastener meets industry standards for dimensional accuracy with 3/8"-16 thread size, 4 1/2" overall length, and 3 1/2" grip length. Material composition and manufacturing processes adhere to RoHS and REACH environmental compliance requirements.
