Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional engineering value through its robust material composition and precision UNC coarse thread design. The cup point tip creates permanent seating in shaft collars, pulleys, and gears, solving critical vibration-induced loosening problems in rotating machinery. With Rockwell C45 hardness, it maintains structural integrity under extreme mechanical stress, while the external square drive ensures secure tool engagement during high-torque installation. The Class 2A thread fit provides optimal clearance for efficient assembly without compromising holding strength, making it ideal for heavy-duty industrial applications requiring reliable positioning and locking capabilities in power transmission systems and precision equipment.
Specification Summary & Compliance
This set screw maintains precise Class 2A thread fit tolerances with 1/2"-13 UNC coarse thread specifications. Manufacturing complies with ASME B18.6.2 standards for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meets REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility in industrial applications.
