Main highlights

• •Nord-Lock wedge-locking washers are made for use with 3/8 inch steel bolts and/or nuts.
• •Each pack contains 20 glued pairs of washers.
• •Applications for Nord-Lock steel washers include general steel applications.
• •Nord-Lock washers utilize tension instead of friction in order to secure bolted joints exposed to severe vibration and dynamic loads. Nord-Lock steel washers promise the highest corrosion resistance on the market.
• •Nord-Lock wedge-locking washers are used in industries such as: energy, robotics, medical, transportation, offshore, mining and quarrying, construction and bridge building, manufacturing and processing, ship building, forestry and agriculture, heavy vehicles, and military.

Main highlights

• •Standard: DIN 25201; For Bolt Diameter: 3/8"; Inside Diameter: 10.6mm / 0.42"; Outer Diameter: 16.6mm / 0.65"; Thickness: 2.5mm / 0.1"; Package Content: 40pcs x Wedge Locking Washers
• •Material: The wedge locking washers are made of manganese steel, providing strength and durability to withstand heavy loads and harsh conditions. The surface coating enhances their corrosion resistance and prolongs their lifespan.
• •Design: These vibration resistant safety washers feature a dual-wedge design with interlocking teeth on both sides. This design creates tension between the bolt and the nut, effectively preventing any loosening caused by vibrations or dynamic forces.
• •Usage: To use these washers, simply place them between the fastener and the mating surface. As the fastener is tightened, the wedges of the washers self-lock and create a powerful clamping force that resists vibration-induced movement, ensuring a tight and secure connection.
• •Application: The wedge locking washers find extensive applications in such machinery, construction, transportation, and infrastructure projects. They are specifically designed for environments with high levels of vibration or dynamic loads.
