Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these black oxide steel screws deliver critical corrosion protection in manufacturing equipment, machinery assembly, and structural frameworks. The fully threaded UNC coarse thread design prevents loosening under vibration while enabling rapid installation in steel-to-steel connections. With 60,000 psi tensile strength and Rockwell B70 hardness, these Phillips pan head screws maintain clamping force in high-load scenarios, reducing maintenance frequency in conveyor systems, hydraulic components, and production line equipment. The Class 2A thread fit ensures consistent engagement while the rounded head profile minimizes snagging hazards in automated environments.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precision engagement. The 5/16"-18 UNC coarse thread maintains standardized compatibility while the 2-1/4" length provides full-thread coverage. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe industrial deployment. Thread direction: right hand, drive size: No. 4 Phillips, head style: pan with standard rounded profile.
