New mechanism's locking nut 'NEW Lock Nut'
Compatible with JIS bolts. Surface treatment is equivalent to SUS304, hot-dip galvanized, trivalent chromate. Sizes range from M6 to M30.
Demonstrates loosening and detachment prevention effects in vibrating environments, single-type locking nut NETIS registration number KK-150023-A.
【Product Overview】A single-type locking nut used on screws in areas subject to vibration, providing anti-loosening and anti-falling effects. The combination of a recessed nut and an eccentric washer exhibits a powerful anti-loosening effect due to the wedging action, even in vibration environments where double nuts would loosen. Temporary tightening can be done by hand. Torque management is required only once.

basic information
【Features】A single-type locking nut used on screws in areas subject to vibration, providing anti-loosening and anti-falling effects. The combination of a recessed nut and an eccentric washer exhibits a powerful 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】Locking nuts used to secure auxiliary facilities such as lighting fixtures and sound-absorbing panels in areas subject 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 measures are necessary in vibration environments.

Applications/Examples of results
【Application】 A locking nut used to secure auxiliary facilities such as lighting fixtures and sound-absorbing panels in places subject to vibrations, such as on bridges. By managing the torque during tightening, it prevents loosening even when subjected to vibrations, eliminating the need for re-tightening during inspections. 【Examples of Achievements】 - Noise barrier installation work - Tunnel lighting equipment installation work - Installation work of rear sound-absorbing panels - Tunnel interior panel work - Sign installation work - Mechanical parking facility equipment - Mega solar facility construction - Inspection path for bridge auxiliary inspections
Detailed information
-
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 concave nut come into close contact, increasing frictional force. 3. The taper of the eccentric washer pushes the concave nut upward, making contact with the threads of the bolt.
