Professional Applications & Engineering Value
This heavy-duty square head set screw addresses critical industrial fastening challenges where maximum torque transmission and vibration resistance are paramount. The black-oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C45 hardness for long-term reliability in machinery, equipment manufacturing, and structural applications. The extended tip design ensures deeper material penetration, creating more secure locking in pulleys, gears, and collars. With 3/4"-10 UNC coarse threads and Class 2A thread fit, this set screw delivers consistent performance in high-vibration environments while meeting rigorous industrial standards for quality and safety.
Specification Summary & Compliance
This 3/4"-10 UNC square head set screw features precise Class 2A thread fit with coarse thread spacing for optimal engagement. The extended tip maintains tight dimensional tolerances (tip length: ±0.005", tip diameter: -0.013" to 0") ensuring consistent performance. Manufactured to ASTM F912 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, this fastener meets the highest standards for industrial applications requiring reliability and regulatory adherence.
