Professional Applications & Engineering Value

This Grade 5 hex head screw delivers exceptional engineering value through its steel construction and cadmium plating, specifically designed to address industrial fastening challenges. The 3/8"-16 UNC coarse thread configuration provides superior grip in soft materials and accelerated assembly times, while the partially threaded design concentrates strength where needed most. With 120,000 PSI tensile strength and Rockwell C25 hardness, this fastener withstands extreme mechanical stress in heavy machinery, structural frameworks, and equipment manufacturing. The external hex drive accommodates high-torque applications, making it ideal for maintenance, repair, and OEM operations where reliability cannot be compromised.

Specification Summary & Compliance

This inch-system fastener features precise Class 2A thread fit tolerances and UNC coarse threading per industry standards. The screw meets MS90725-64 military specifications for quality assurance and demonstrates compliance with relevant industrial fastening standards. Manufacturing follows rigorous quality control processes to ensure dimensional accuracy and performance consistency across all applications.
