Factory directly supply quality DIN6798 serrated lock washers made in China. Jiaxing Aoke hardware as a experienced manufacturer and have advanced stamping equipment for manufacturing serrated locking washers.The DIN6798A external serrated locking washer and the DIN6798J internal serrated locking washer can effectively prevent the loosening of the bolt's threads due to vibration and impact. When the bolt and the DIN6798 serrated locking washer are installed together, the serrated washer generates a reverse rebound force through the elastic deformation of the material to prevent the thread from loosening. The serrations of the DIN6798A serrated locking washer are on the outer side. The DIN6798J internal serrated locking washer adopts an internal serrated design and directly engages with the bolt thread. If you interested in DIN6798A and DIN6798J toothed washers, please contact with us.

Jiaxing Aoke is a Chinese factory to produce DIN6797 toothed lock washer, our factory has obtained ISO9001 certificate. DIN6797A external toothed lock washers and DIN6797J internal toothed lock washers are the most commonly used during assembly. The function of the DIN 6797 toothed locking washer is to prevent the threads from loosening due to vibration and impact. DIN 6797 series lock washers are non-spring self-locking washers. Their core locking principle is achieved through precision-machined serrations on the washer surface, rather than elastic deformation. The working principle of the DIN6797 toothed washer is that when the bolt or nut is tightened, the DIN6797 teeth lock washer is forced to generate pressure, and the bite effect of the serrations prevents the thread from loosening due to vibration and load, thereby achieving an anti-loosening effect.

As the professional manufacturer in China, Jiaxing aoke would like to provide you DIN7980 spring washers. You can rest assured to buy lock washers from our factory. DIN7980 spring lock washer is the German Industrial Standard for "Spring Washers for Cylinder Head Screws." Compared to the commonly used DIN127 spring washers, DIN7980 spring washers have a smaller outer diameter and are specifically designed for use with DIN 912 hexagon socket head screws. Why are we choosing stainless steel to produce DIN7980 spring lock washers? Stainless steel 304 (A2)/316 (A4) stainless steel offers corrosion resistance levels that cover atmospheric, freshwater, mild acid and alkaline, and marine environments. Stainless steel DIN7980 spring washers have a bright surface, require no electroplating, eliminate the risk of hydrogen embrittlement, and are RoHS/REACH compliant.

Aoke hardware strictly adhere to the ISO 9001 quality management system. From the warehousing of raw materials to the delivery of finished flange bolts, every process undergoes rigorous inspection to ensure that each torx flange bolt complies with international standards (such as DIN, ISO, ASME, etc.) and the customized requirements of our customers. Torx hex head flange bolts combine a hexagonal flange head with a Torx drive mechanism.This Torx drive mechanism provides superior anti-slip performance compared to traditional Phillips or Hex socket bolts. Made of high-quality stainless steel 304 and 316, the hexalobular socket hex head flange bolts offer excellent corrosion resistance and high strength, meeting the mechanical performance requirements of A2-70, A4-70, and even A2-80 and A4-80.

Jiaxing Aoke hardware is a Chinese DIN251 hex socket flange screws producer and supplier. Our factory are ISO9001 certified and currently have a large amount of inventory. DIN251 hexagon socket head screws with serrated flange, with their "hexagon socket head + flange face" design, offer irreplaceable advantages in connection scenarios requiring high strength, compact space, and anti-loosening. The DIN251 flange screws feature a cylindrical head with a hexagon socket recess at the top. This hexagonal drive mechanism transmits greater torque (over 30% higher than similar cross-recessed screws) and prevents slippage during installation with an electric screwdriver. The DIN251 hex socket screw's flange is integrally molded, with a larger diameter than the head and featuring anti-slip serrations. This design eliminates the need for additional washers, streamlining the assembly process.
