Fang bolt
Fang Screw (also known as anti-slip screw, toothed screw, or knurled screw) is a specially designed fastener typically used in elevator belts or other transmission systems to enhance friction, prevent slippage, or secure belt joints. Its defining feature is the presence of serrations, grooves, or special textures (i.e., "teeth") on the screw head or thread, providing stronger gripping force and anti-loosening performance.
1. High Anti-Slip Performance:
The serrated design effectively increases friction with belts, metal, or rubber contact surfaces, preventing loosening or slippage.
2. Vibration-Resistant & Anti-Loosening:
The toothed structure maintains secure fastening even in high-vibration environments, making it suitable for high-speed elevator systems.
3. Wear Resistance:
Made from high-strength materials or treated with surface coatings (e.g., quenching, plating) to extend service life.
4. Easy Installation:
Self-tapping serrated screws can be directly driven into the base material, eliminating the need for pre-drilling.
5. Versatile Compatibility:
Available in different tooth densities and hardness levels to match various belt materials (rubber, PVC, steel cord, etc.).
Elevator Belt Systems:
Used for securing belt joints or installing belt clamps to prevent misalignment and slippage during high-speed operation.
Commonly applied in bucket elevators across mining, cement plants, grain conveying, and related industries.
Transmission Devices:
Serves as an auxiliary fastener in sprocket, gear, or timing belt transmissions to enhance drive stability.
Industrial Equipment:
Ideal for anti-loosening applications in vibrating screens, conveyors, heavy machinery, and similar equipment.
Maintenance & Retrofitting:
Provides quick and reliable solutions for old belt replacement or temporary reinforcement.
Fang Bolt
Tolerance quality is 6g,mechanical properties grade is greater than 4.8-5.6.Surface treatment is galvanized.
Applied to lift heavy capacity materials and can be used in highline speed.It is suitable for plastic bucket and steel bucket.
Especially for install big capacity bucket or big convexity bucket.Italso can borne heavy impact load during the operation of the equipment.
