Why Knurled Cup Point Set Screws?

The knurled cup point set screw design is engineered to dig into the contact surface, increasing friction and preventing loosening under high torque or repeated movement. These set screws provide excellent holding power, making them ideal for applications requiring secure, long-lasting fastening in high-vibration or heavy-load environments.

Ideal Applications

• Collars, Gears, & Pulleys on Shafts
• Heavy Equipment & Industrial Machinery
• Automotive & Small Engine Assemblies
• High-Torque & High-Vibration Environments
• Maintenance & Repair Operations (MRO)

Installation Tips

• Use a correctly sized hex socket/Allen wrench to ensure a proper fit.
• Apply even torque to prevent over-tightening or thread damage.
• Ensure the contact surface is clean and free of debris for optimal grip.
• Regularly inspect in high-vibration environments to maintain tightness.
