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.

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.
