[NETIS Registration] New mechanism's locking nut "NEW Lock Nut"
Compatible with JIS bolts. Surface treatment equivalent to SUS304, hot-dip galvanized, trivalent chromate. Sizes range from M6 to M30.
Exhibits anti-loosening and anti-falling effects in vibrating environments! Easy to use on-site with hand-tightening allowed! This is a single-type anti-loosening nut registered with NETIS.
The NEW lock nut is a high-performance nut that combines four effects: "bite," "wedge," "anti-loosening," and "amplification," along with the excellent workability of a single nut type. Its powerful anti-loosening effect and high work efficiency have been proven in environments where high safety is required, such as highway bridges and tunnels. 【Examples of Achievements】 - Sound barrier installation work - Tunnel lighting equipment work - Backside sound-absorbing panel installation work - Tunnel interior panel work - Sign installation work - Mechanical parking facility - Mega solar facility work - Inspection paths for bridge accessories *For more details, please download the catalog and contact us.

basic information
【Features】A single-type locking nut used on screws in areas subjected to vibration, providing anti-loosening and anti-falling effects. The combination of a concave 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】Locking nuts used to secure auxiliary facilities such as lighting fixtures and sound-absorbing panels in vibration-prone areas like 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
【Purpose】 A locking nut for securing auxiliary facilities such as lighting fixtures and sound-absorbing panels in locations subject to vibrations, such as on bridges. By managing the torque during tightening, it prevents loosening even under vibration, eliminating the need for re-tightening during inspections. 【Examples of Achievements】 - Noise barrier installation work - Tunnel lighting equipment installation work - Installation work for 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 the 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.
