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.
