Professional Applications & Engineering Value
This brass set screw delivers exceptional value in applications where corrosion resistance and precision threading are critical. The UNC coarse thread configuration with Class 3A fit provides superior vibration resistance in machinery, automotive, and electrical components where brass' non-sparking properties enhance safety. The headless design with hex drive allows flush mounting in precision equipment while maintaining high torque capability. Engineered to Rockwell B55 hardness, this fastener offers the perfect balance between machinability and strength, preventing galling while ensuring reliable performance in industrial set screw applications requiring repeated adjustments.
Specification Summary & Compliance
This precision fastener features 5/16"-18 UNC coarse threads with Class 3A thread fit (tight tolerance for external threads), 5/8" length, and 5/32" hex drive. Manufactured to ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict material restrictions.
