Professional Applications & Engineering Value
These black oxide steel rounded head Phillips screws deliver exceptional engineering value in industrial fastening applications where corrosion resistance and consistent performance are critical. The 2-56 UNC coarse thread configuration provides excellent grip in softer materials and rapid assembly, while the fully threaded design ensures maximum contact surface for vibration resistance. The combination of 60,000 psi tensile strength and Rockwell B70 hardness addresses common failure points in machinery, electronics, and equipment assembly, preventing stripping and maintaining clamp load under dynamic stresses. The standard pan head profile with No. 1 Phillips drive offers reliable torque transmission without specialized tools, making these screws ideal for maintenance operations and production lines requiring efficient, repeatable fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 2-56 UNC coarse threads (0.086" diameter, 3/8" length) ensuring dimensional consistency across applications. Complies with ASME B18.6.3 mechanical and dimensional specifications for slotted and Phillips drive machine screws. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming adherence to restricted substance guidelines for industrial use.
