Professional Applications & Engineering Value
These heavy-duty hex head screws deliver exceptional engineering value in demanding industrial applications where corrosion resistance and mechanical strength are critical. The 18-8 stainless steel composition provides superior protection against rust and chemical degradation, making these inch fasteners ideal for chemical processing equipment, marine environments, and food processing machinery. The ASTM A193 Grade B8 certification ensures material integrity under high-temperature conditions, while the coarse UNC thread design prevents cross-threading and facilitates rapid assembly in production environments. The partial threading and precise Class 2A thread fit enable controlled clamping force distribution, solving vibration-induced loosening challenges in heavy machinery and structural applications.
Specification Summary & Compliance
This 7/8"-9 UNC hex head screw features precise Class 2A thread fit tolerances with coarse thread spacing and partial threading configuration. Manufactured to ASTM A193 Grade B8 specifications with dimensional compliance to UNC thread standards. The fastener delivers 75,000 psi tensile strength and Rockwell B96 hardness with full traceability to industrial standards. Compliant with RoHS and REACH environmental regulations for industrial use.
