Pack of 220 Inner Tooth Clamping Washers M6 x 15 mm, Securing Washers Manganese Steel Inverted Locking Washer Set for Screws Bolts Nut Rods, Black

What is it? An internally toothed lock washer is a vibration resistant fastener in most mechanical devices, with inward facing teeth that dig into both the screw head and the mounting surface. Mainly used in industrial, automotive and machine applications to provide fastening, support and damping functions. What do I get? Internal toothed locking washers. Size: M6 x 15 x 1.5 mm / 0.24 x 0.59 x 0.06 inches (ID x OD x thickness); Material: 65 manganese steel; Design: flanged. Package includes: 220 pieces slide-on star locking discs. What are the advantages of this product? Compared to traditional gaskets, the inward facing teeth of the star lock washers can dig better into the mounting head and mounting surface, creating effective torque that prevents easy release due to frequent vibrations. Made of durable and high-strength 65Mn steel material, with corrosion and oxidation resistance, which ensures long-term use. How to use it? Make sure the washer fits the shaft of the fastener. Place directly under the mounting head or nut, with the teeth towards the fastener. The flat side lies on the work surface. Tighten the fastener firmly. The inner teeth grip both into the fastener and the surface, creating friction that prevents loosening due to vibration. What should I pay attention to? Before purchasing this product, please check the product specifications to make sure it is the right size for your needs.
