Product Description

Characteristics

Cold Heading Wire, Cold Forming Wire and CHQ Wire are used for the production of fasteners including bolts, nuts, and screws. Fasteners have traditionally been manufactured using the thread cutting or hot working method. However, the trend is moving towards using the cold working process to enhance productivity and to keep the cost down. Cold heading wire, therefore, possesses excellent workability and surface quality for the cold working process to take place.
