Wire

The manufacturing process of our spheroidizing annealing wire is using cold heading quality wire rod as the base material through four steps as intermediate drawing, spheroidization, pickling and coating, and skinpass. Intermediate drawing is the wire rod has been rust-removed and drawn as small diameter wire through the drawing dies. Spheroidizing treatment is to spheroidize the Intermediate drawn wire by spheroidizing annealing furnace.

The fastener items often apply this material to self-drilling screws, wood screws, self-tapping screws, and drywall screws etc.
