Professional Applications & Engineering Value
Engineered for industrial assembly systems, these black-oxide alloy steel screws address critical challenges in vibration-prone environments and corrosive conditions. The 6-32 UNC coarse thread configuration combined with Class 3A thread fit ensures rapid installation while maintaining consistent clamping force in electronic enclosures, machinery guards, and automated equipment. The fully threaded design with integrated flange eliminates the need for separate washers, reducing component count and assembly time. With 120,000 psi tensile strength, these rounded head screws provide reliable performance in high-stress applications where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precision thread standards with Class 3A UNC thread fit and coarse thread spacing for optimal engagement. The black-oxide alloy steel construction meets ASTM F835 specifications for mechanical properties and dimensional accuracy. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. Thread diameter of 0.138" with 3/4" length provides consistent dimensional stability across production batches.
