Why Choose Cup Point Set Screws?

The cup point design has a concave tip that bites into the contact surface, delivering exceptional traction and vibration resistance. This helps minimize slippage, making cup point set screws an ideal choice for high-torque or alignment-sensitive machinery.

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

• Use an appropriately sized hex key (Allen wrench) to avoid drive damage.
• Apply steady torque to prevent thread stripping or rounding the drive.
• Ensure mating surfaces are clean and free of debris for optimal grip.
• Consider a thread-locking compound in high-vibration scenarios to maintain tightness.
