About This Product

Nord-Lock washers, which feature a wedge locking mechanism, use axial force rather than friction to physically prevent bolt connections from loosening. Nord-Lock washers greatly reduce the risk of loss due to unexpected production stoppages, accidents, warranty claims, etc., contributing to improved production efficiency and reduced maintenance costs.

■Advantages

・Wedge locking mechanism prevents rotation from loosening - Quick and easy installation and removal using only common tools ・The anti-loosening function does not change even if lubricant is used. ・Precise axial force management is possible because no loosening occurs. ・Temperature characteristics similar to bolts and nuts ・Not infinite, but reusable ・Since no load is placed on bolts and nuts, reusability of bolts and nuts is ensured. ・Designed to withstand heavy loads by increasing surface hardness ・If you use a wide type SP washer with a larger outer diameter, it will be extremely effective when the long hole or pilot hole is large, when the mating material is soft, or when fastening to a painted surface. ・High corrosion resistance ・Can also be used with high-strength bolts of strength classification 12.9 (ASTM A574) ・Achieves firm fastening even in places where the bolt length is short

■SP washer (wide type)

Nord-Lock SP washers are wide type washers that have the same wedge lock mechanism as standard washers. SP washers should be used in conjunction with flanged hex bolts and nuts (IOS4161, 4162) for large holes that exceed the bolt hole diameter specified in JIS B 1001, long holes, or when the mating material is soft.

■Specifications
