basic information

【Features】A single-type lock nut used on screws in areas subjected to vibration, providing anti-loosening and anti-falling effects. The combination of a recessed nut and an eccentric washer exhibits a strong anti-loosening effect due to the wedging action, even in vibration environments where double nuts would loosen. Preliminary tightening can be done by hand. Torque management is required only once. 【Main Applications】Lock nuts used to secure auxiliary facilities such as lighting fixtures and sound-absorbing panels in areas subjected to vibration, such as on bridges. When tightened with torque management, they do not loosen even under vibration, eliminating the need for re-tightening during inspections. Additionally, a range of universal sizes and materials is available for use in other areas where anti-loosening and anti-falling effects are necessary in vibration environments.

Price information

Detailed information

  • 緩み止めのメカニズム_スクエア.jpg

    Mechanism of the locking device 1. When the concave nut is tightened, the eccentric washer presses against the threads of the bolt. (Wedge action) 2. The bolt and the concave nut come into close contact, increasing frictional force. 3. The taper of the eccentric washer lifts the concave nut, making contact with the threads of the bolt.
