Professional Applications & Engineering Value
This Grade 8 hex head screw delivers exceptional engineering value for heavy-duty industrial applications where failure is not an option. The steel construction combined with 150,000 PSI tensile strength and Rockwell C32 hardness ensures reliable performance in high-stress environments including machinery assembly, structural steel connections, and equipment manufacturing. The 7/16"-14 UNC coarse thread provides excellent engagement in various materials while resisting vibration-induced loosening. The flanged design eliminates the need for separate washers, reducing component count and installation time. With partial threading, the unthreaded shank section maintains superior shear strength, making these industrial fasteners ideal for pivot points and structural joints subject to dynamic loads.
Specification Summary & Compliance
This inch system fastener features precise Class 2A thread fit per UNC standards with dimensions including 7/16"-14 thread size, 2 3/4" length, and 15/16" flange diameter. Manufactured to IFI 111 specifications meeting SAE J429 Grade 8 requirements for mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
