• Reliable thread engagement with Class 2A thread fit, providing consistent performance and ease of assembly in industrial applications
• Secure component positioning thanks to the cup tip design, which digs into surfaces to prevent axial movement of parts
• Guaranteed quality and safety through compliance with ASME B18.6.2 manufacturing standards, ensuring dimensional accuracy and performance reliability
• Environmentally responsible sourcing with full RoHS 3 and REACH compliance, meeting global regulatory requirements for hazardous substances

Professional Applications & Engineering Value

This 1/2"-13 UNC steel set screw is engineered to solve critical challenges in industrial assembly and machinery. The coarse thread spacing and Class 2A thread fit provide excellent grip and vibration resistance, making it ideal for securing pulleys, gears, and collars on shafts where rotational forces are prevalent. The square head with external square drive allows for high-torque installation, preventing cam-out and ensuring a secure fit in heavy-duty applications. Manufactured from high-strength steel and hardened to Rockwell B80, it withstands repetitive stress and harsh operating conditions. The cup tip design offers superior biting action into materials, preventing component slippage and maintaining precise alignment in automotive, aerospace, and manufacturing equipment.

Specification Summary & Compliance
