Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 18-8 stainless steel hex head screws deliver exceptional performance where corrosion resistance and structural integrity are paramount. The 5/16"-24 UNF fine threading with Class 2A fit ensures precise engagement in critical assemblies, reducing the risk of thread stripping in soft materials or thin-walled applications. The external hex drive configuration accommodates high torque requirements during installation, making these partially threaded screws ideal for machinery, equipment manufacturing, and structural frameworks where vibration resistance and long-term reliability are essential. With 80,000 psi tensile strength and Rockwell B70 hardness, these fasteners maintain their mechanical properties in demanding environments while the 4 1/2" length provides sufficient engagement for thick material sections.
Specification Summary & Compliance
This 5/16"-24 UNF hex head screw features precise Class 2A thread fit per UNF standards with 0.3125" thread diameter and fine thread spacing. The 4 1/2" length includes 7/8" minimum thread length with partial threading configuration. Manufactured from 18-8 stainless steel with Rockwell B70 hardness and 80,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial applications.
