Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 5/16"-24 UNF hex head screws deliver critical performance advantages where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making these fasteners ideal for marine equipment, food processing machinery, and outdoor structural applications. The Class 2A thread fit ensures consistent engagement with mating components, reducing assembly time and preventing thread damage during installation. With 80,000 psi tensile strength and Rockwell B70 hardness, these partially threaded screws maintain clamping force under vibration and load variations, while the external hex drive allows for high-torque installation in confined spaces. The fine thread configuration enhances joint stability in materials prone to loosening under dynamic conditions.

Specification Summary & Compliance

This 5/16"-24 UNF hex head screw features precision Class 2A thread fit per UNF standards with a thread diameter of 0.3125" and fine thread spacing.
