Why Choose Cup Point Set Screws?

The cup point design has a concave tip that bites into the contact surface, offering exceptional grip and vibration resistance. This is optimal for applications where a strong hold and minimal slippage are critical—such as alignment-sensitive machinery, gears, and collars.

Ideal Applications

• Machinery & Equipment Alignment
• Automotive & Aerospace Fastening
• High-Vibration & High-Torque Assemblies
• General Maintenance & Repair (MRO)
• Securing Gears, Collars, & Pulleys

Installation Tips

• Use a compatible hex key (Allen wrench) to prevent rounding out the drive.
• Apply consistent torque to avoid thread or drive damage.
• Ensure mating surfaces are clean and free of debris for optimal grip.
• For high-vibration setups, consider using a thread-locking compound to maintain tightness.
