"Hope for the best, but prepare for the worst ."

Hitting on the idea of ancient Japanese architecture, HARDLOCK invented the HARDLOCK Nut with a wedge-shaped construction. This provided an elegant solution with lower costs and better workability. The HARDLOCK Nut ensures a perfect locking performance which keeps any application safe and secure.


Drastic reduction of railway maintenance operation

As of now in Japan 20 thousand hardlock nuts are installed in 16 coaches of a train set. Additionally at the seam plates between rails hard lock nuts are used as fishing bolts at almost every rails in Japan. JR Tokai noticed Hardlock nuts had not only reduced maintenace work but had improved safety, and therefore had commended the company in 2014 for Hardlock's contribution to provide traffic safety.

Moreover its performance had been highly evaluated by Taiwan High Speed Rail and 4 million nuts have been used at seam plates of 300 km rail line from Taipei to Kaohsiung. In U.K. its reputation assisted to rill out . After the U.K. derailment in 2007, BBC reported if U.K. could have avoided traffic accident if hardlock nuts were used at railroad switches.


Its application has expanded to constructions such as Tokyo Sky Tree where 400 thousand nuts have been used. Wakabayashi could be able to provide some proof of long lasting selflocking function for 100 years and ordered operators to teach way to fasten nuts by himself. Based on his firm belief Wakabayashi is focusing the corporate philosophy "Safety is Power".
