Professional Applications & Engineering Value
These 4-40 UNC rounded pan head Phillips screws deliver exceptional engineering value in industrial assembly applications where corrosion resistance and mechanical strength are paramount. The black oxide steel construction provides superior protection against environmental factors, while the coarse thread design ensures reliable performance in softer materials and faster installation times. The pan head profile with Phillips drive offers a low-profile solution that resists snagging while providing excellent torque transmission. Engineered to withstand rigorous industrial environments, these fully threaded screws maintain their integrity under vibration and load stress, making them ideal for machinery, equipment manufacturing, and electronic enclosures where 60,000 psi tensile strength and consistent performance are critical requirements.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread specifications ensuring proper engagement and interchangeability. These rounded pan head screws comply with ASME B18.6.3 manufacturing standards for consistent quality and performance. The products are fully compliant with RoHS 3 (2015/863/EU) regulations and meet REACH (EC 1907/2006) requirements for environmental safety, making them suitable for use in regulated industries and international markets.
