Why Choose Cup Point Set Screws?

The cup point is the most commonly used set screw design, providing excellent holding power with minimal surface damage. The slightly concave tip creates a strong, vibration-resistant hold, making these screws ideal for locking components, securing shafts, and preventing movement. The Zinc-Bake CR+3 finish further enhances durability and resistance to corrosion.

Ideal Applications

• Locking Gears, Pulleys, and Shafts
• Precision Machinery & Equipment
• High-Torque Fastening & Vibration Resistance
• Component Securing in Industrial Applications
• Corrosion-Resistant Fastening in Harsh Environments

Installation Tips

• Use a properly sized hex key (Allen wrench) to prevent stripping.
• Apply steady torque to ensure a firm grip and secure hold.
• Ensure surfaces are clean and free of debris before installation.
• Consider using a thread-locking compound for additional security in high-vibration applications.
