Lockwashers are essential components used to prevent threaded fasteners from loosening under vibration, shock, or heavy dynamic loads. Available in a wide range of styles, materials, and finishes, lockwashers provide mechanical locking action through tension, friction, or serrated bite, ensuring secure, reliable fastening across industrial, structural, and high-performance applications.
Our selection includes advanced Nord-Lock™ wedge-locking washers in both steel and stainless steel, engineered to maintain clamp load even in extreme vibration environments. We also offer wedge lock washer options for applications requiring maximum joint security. Traditional split lock washers are available in multiple configurations, including regular, heavy, hi-collar, thru-hardened, heat-treated, and alloy steel varieties, with finishes such as plain, Zinc Cr+3, zinc yellow, and hot-dip galvanization to suit environmental or corrosion-resistance requirements.
For applications demanding strong biting action, we provide internal and external tooth lock washers in plain and Zinc Cr+3 finishes, including specialized metric styles such as DIN 6797J internal tooth lockwashers, DIN 6798A external tooth serrated lockwashers, and DIN 6797A external tooth lockwashers. Combination internal/external tooth lock washers are also available for enhanced grip on softer materials.
Our metric offerings include Metric Split Lock Washers DIN 127B in zinc yellow, as well as thru-hardened DIN 127 lockwashers in plain and Zinc Cr+3 finishes. Additional specialty options include Monel lock washers for superior corrosion resistance and Metric Hi-Collar Lockwashers DIN 7980 for applications requiring higher tension and reduced surface area.
With a full range of materials, hardness levels, and coatings, our lockwasher selection provides dependable performance for everything from general-purpose fastening to demanding industrial and structural applications.
