Why Choose Cup Point Set Screws?

The cup point design has a concave tip that bites into the contact surface, offering exceptional traction and vibration resistance. This ensures minimal slippage, making cup point set screws particularly well-suited for high-torque or alignment-sensitive applications.

Ideal Applications

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

Installation Tips

• Choose the appropriate hex key (Allen wrench) to prevent drive damage.
• Apply steady torque to avoid thread stripping or rounding the drive.
• Ensure mating surfaces are clean and debris-free for optimal grip.
• In high-vibration setups, a thread-locking compound can help maintain tightness.
