Professional Applications & Engineering Value
These Grade 5 hex head screws deliver critical performance advantages in heavy-duty industrial applications where fastener failure is not an option. The UNF fine thread configuration provides superior resistance to vibrational loosening compared to coarse threads, while the zinc plated finish creates a protective barrier against corrosion in challenging environments. The external hex drive design enables high-torque installation without stripping, and the fully threaded construction ensures maximum engagement depth. Engineered to ASME B18.2.1 standards, these screws offer predictable performance in machinery, structural assemblies, and equipment requiring 120,000 psi tensile strength with consistent Rockwell C25 hardness.
Specification Summary & Compliance
This 3/8"-24 UNF hex head screw features precise Class 2A thread fit tolerances and complies with ASME B18.2.1 and SAE J429 Grade 5 specifications. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental responsibility while delivering 120,000 psi tensile strength and Rockwell C25 hardness in a 1/2" length, fully threaded configuration with right-hand thread direction.
