1 . Harden material
Stainless steel wood screws with good ductility and hardness is up to HRC 20.
2 . Corrosion resitance
Sainless steel wood screws are not rusted in years .
3 . Fast drilling performance
Wood tapping threads can cut and drill workpieces fast .
4 . Resitant high temperature
5 . Nice and smooth surface .
No burrs or scratch
6 . Environmental friendly
7 . Solid stability .
8 . Effective working .
Strict sizes and tolerances ensure stainless steel wood screws to be operated smoothly .
9 . Long-service .
Stainless steel wood screws are normally used for secure wooden or plastic or chipboard ,especially for furniture .
1 . Use a socket wrench or spanner to operate stainless steel wood screw .
2 . The thread moving direction is from right to left , and back out in reverse direction .
3 . Do not use a sharp tool or bladed tool to drive the screws .
4 . Do not scratch the screw in harden something in order to keep bright surface .
5 . Keep screws in the dry warehouse .
