The "Nortlock Washer" is a product that, when placed under bolts and nuts and tightened once, exhibits a powerful anti-loosening effect. By inserting a pair of washers with a cam surface and radial rib surface, the axial force increases when loosening forces are applied, achieving anti-loosening without relying on friction. It is resistant to vibrations and impacts, providing a long-lasting anti-loosening effect. 【Features】 ■ No issues when used in conjunction with hot-dip galvanized coatings ■ No need for double nuts; simply insert into a single nut ■ Allows for easy and reliable fastening regardless of the operator's skill level ■ Suitable for maintenance in hard-to-reach areas such as high places or narrow spaces ■ NETIS registered product (KKK-190002-A) *Documentation introducing product features can be viewed from the "Download" section.

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.
