 2. Applications:

    

     Through ordinary passivation, the antioxidant and rust-proof capacity of self drilling screws which our factory produced increased by more than 5 times, and the neutral salt spray test has achieved more than 50 hours. Extending the working life and increasing the reliability.

 
     The properties of drilling screw : 1) Exact forging standard of knife edge and high hardness of surface make it easy to drill. 2). The Special technology treatment of the surface makes the product anti-corrosion , antirust and durable. 3) Using the advanced technology to control the core hardness, avoiding rupture effectivity
