No more lock nuts that were used in hundreds and thousands! An example that also contributed to vehicle weight reduction.
We would like to introduce a case study of Tokai Railway Company (JR Tokai) that adopted Nord-Lock products. The company has had skilled workers who meticulously maintain and inspect their systems day and night to ensure safety, which required a tremendous amount of effort and time. Therefore, they adopted our "Nord-Lock Washer." This product has a mechanism that prevents loosening and rotation under even the harshest vibration environments, significantly advancing this long-standing issue. 【Case Overview】 ■ Customer: Tokai Railway Company (JR Tokai) ■ Product: Shinkansen N700 Series Vehicles ■ Adopted Product: Nord-Lock Washer *For more details, please refer to the PDF document or feel free to contact us.

Company information
Nortlock Japan Co., Ltd. aims to be a partner in solving all bolt fastening challenges, centered around four brands: the "Nortlock Washer," a locking mechanism that does not rely on friction and prevents loosening; the "Superbolt," which allows enormous bolts and nuts that cannot be tightened by hand to be tightened with just one torque wrench; the "Boltight," which can simultaneously tighten multiple large-diameter bolts with uniform pressure; and the "Expander," a pivot pin for construction and heavy machinery that can be used semi-permanently.
