The Fine U Nut is designed to prevent the loosening of screws in specific mechanical connections and is a special nut used for stable rotation in rotating machinery such as bearings.

The Fine U Nut has a U-shaped design, which allows for fine torque adjustments unlike regular nuts, and it provides stable rotation with minimal loosening.

Additionally, it can be used without the need for separate washers or shaft machining, making it relatively easy to install. Due to these features, the Fine U Nut is widely utilized in various mechanical industries.

The Fine U Nut has more precise threads compared to standard nuts. This allows for more threads per unit length due to the smaller pitch, providing greater frictional force when tightened.

• Used when extremely precise torque (tightening force) and screw tightening are required
• Engine components, high-speed rotating equipment, precision measuring instruments

• Used in equipment sensitive to vibration or shock
• The small thread pitch prevents the screws from loosening
• Enhances the stability of the equipment

• Maintains stable tightening in high temperatures, low temperatures, and humid conditions

• Used in areas requiring precise assembly (weight reduction)

• Easy to install without keyway machining on the shaft or the use of washers

• Maintains loosening torque even with repeated use, offering excellent durability
• Strong resistance to vibration, ensuring stable rotation

• Allows for fine adjustments, making torque management easy
• Improves the rotational balance of the shaft and overall machine performance

• Used in various rotating machinery such as motors, pumps, and compressors
• Ensures stable rotation of bearings across the mechanical industry
