Simultaneously solve both "rotational looseness" caused by reverse rotation and "non-rotational looseness" that does not involve rotation!
The "Nortlock X Series" is a product that addresses both "rotational loosening" and "non-rotational loosening" with a single solution. By combining the spring effect (which compensates for the reduction in axial force due to non-rotational loosening) and the wedge locking function (which prevents rotational loosening), it eliminates the need to only address the higher-risk issues or to complicate the work process by combining multiple products. It is used in various bolt fastening applications across the global railway industry, including bogies, couplers, brake systems, outfitting, track maintenance, and sleepers. 【Features】 ■ A single product that addresses both rotational and non-rotational loosening ■ Multi-wedge lock mechanism ■ Numerous certifications, primarily in Europe ■ Size (steel): M6 to M20 *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.
