Introduction
The document introduces the FYH Bullet Point set screw, developed by Nippon Pillow Block Co., Ltd., designed for severe vibration and high-speed applications. It highlights the innovative design that enhances holding power by expanding the threads outward.

Specifications
The Bullet Point set screw is a one-piece ball point set screw that expands the threads as it contacts the shaft surface. This expansion increases holding power, especially in environments with significant vibration.

Vibration Test Results
- W point set screw slipped at 1,000 hours.
- Ball point set screw came loose at 2,860 hours.
- Bullet Point set screw maintained its hold beyond 3,000 hours under heavy vibration.

Design and Functionality
The Bullet Point set screw's design allows the threads to expand up to and beyond the elastic limit, maximizing holding power. The point's thickness is optimized for easy expansion, reducing potential damage from vibration, shock load, and high speed.

Implementation
The Bullet Point set screw, with suffix code G23, will become the standard set screw in 2010. The design is patent pending.

Conclusion
The FYH Bullet Point set screw offers superior performance in high-vibration and high-speed environments, providing a reliable solution for maintaining secure connections.
