Can't we apply the principle of the wedge? The first product we developed and completed based on this theme was the Hard Lock nut.
The locking energy inherent in this nut maintains a completely fastened condition that is totally uninfluenced by external vibration or impact shock.This type of nut is being used to support safety on railways, expressways, bridges, high-rise buildings, industrial machinery, public facilities, etc., as a secure fastening nut for joining many kinds of parts.
Besides packing a powerful loosening stopping effect that no other locking nut can match, the Hard Lock nut features excellent workability, easy tightening and removal capability, and the economic benefit to the user of being totally maintenance free, as well as boasting an actual record of proven high reliability.
Born out of the pursuit of safety, the Hard Lock nut will continue to display its power to protect the safety of equipment, infrastructure and society in a broad range of applications in all sorts of unseen locations.
