Why Knurled Cup Point Set Screws?

The knurled cup point set screws are engineered to dig into the contact surface, preventing slippage and ensuring a secure hold under high torque or vibration. This design makes them ideal for mechanical assemblies requiring strong, long-lasting fastening.

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 properly sized hex socket/Allen wrench for the best fit.
• Apply even torque to ensure a secure hold without damaging threads.
• Ensure the contact surface is clean and free of debris for maximum grip.
• Inspect periodically in high-vibration settings to maintain tightness.
