Why Knurled Cup Point Set Screws?

The knurled cup point design features serrated edges that dig into mating surfaces, significantly reducing loosening due to vibration or torque. This makes them particularly effective in industrial applications where maintaining a secure hold is critical, even under harsh operating conditions.

Ideal Applications

• Heavy Equipment & Machinery
• Automotive & Truck Repair
• Construction & Industrial Assemblies
• Power Transmission Components (Collars, Gears, Pulleys)
• Rotating & High-Torque Applications

Installation Tips

• Use a hex socket/Allen wrench correctly sized for the internal drive.
• Apply consistent, even torque to secure without over-tightening.
• Ensure the contact surface is clean and free of debris for optimal grip.
• Periodically check for proper tightness in high-vibration environments.
