The technology can prevent nuts from working loose in extreme shockwave and vibration through attaching the special nylon widely utilized in the US and some of EU Countries. The special nylon used in the technology has an advantage of heat. With the advantage, the technology can be utilized longer than other products used in developed countries such as the US, Japan and some EU Countries. For instance, U.S. and European product is only for disposable usage and Japanese Hard Lock’s product can be reused 3 to 5 times; however, this technology itself can be reused more than 30 times – almost infinitely, and therefore it can reduce the cost of price and also reduce carbon emission. Thus, it can contribute to self-sustaining clean industry. Japanese hard lock uses 2 nuts, and consequently has a critical weakness for usability.

It can tow away safely for the post-earthquake occurrence of vibration and shockwave; It can prevent the destruction and harm from earthquake. It has a function to prevent nuts from working loose which can be caused by constant effect of wind and vibration occurring on power plant tower, heavy equipment, industrial machine, vehicle, airplane, tank, space industry equipment and so on. Moreover, it can prevent loose stopping, and it can be used safely in the circumstance of extreme heat.
