Professional Applications & Engineering Value
These black oxide steel screws with 5-40 UNC coarse threading deliver exceptional performance in industrial assembly where vibration resistance and durability are critical. The rounded pan head design provides a low-profile finish while the No. 2 Phillips drive enables efficient installation in confined spaces. Engineered with Class 2A thread fit, these fully threaded fasteners maintain consistent clamping force in machinery, electronic enclosures, and automotive components. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance under mechanical stress, while the black oxide surface treatment offers moderate corrosion protection for indoor industrial environments.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerance for precise engagement. Features 5-40 UNC coarse threads with right-hand orientation and full threading along the 1/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black oxide steel construction meets industrial requirements for strength and durability while maintaining regulatory compliance for global manufacturing applications.
