• Coarse UNC threading enables quick assembly and reduced cross-threading risk in production lines

Professional Applications & Engineering Value

Engineered for industrial machinery, equipment panels, and structural assemblies, these 6-32 UNC coarse thread hex head screws solve critical fastening challenges. The steel construction with zinc plating combats oxidation in humid or outdoor settings, while the external hex drive supports high-torque applications without stripping. With a 60,000 PSI tensile strength and Rockwell B69 hardness, they prevent failure under dynamic loads and repeated disassembly. Ideal for automotive, HVAC, and metal fabrication, these screws ensure long-term reliability where coarse thread fasteners are specified for rapid installation and vibration resistance.
