Product we sell
We sell CHQ Steel Wire used to manufacture fasteners such as screws, rivets, etc.
Cold Heading Steel Wire is a specially processed wire used primarily in the manufacturing of fasteners like bolts, screws, nuts, and rivets through a cold forming (or cold heading) process. This process shapes the metal at room temperature using high pressure rather than heat, which preserves the material’s strength and integrity.
Key Features of Cold Heading Steel Wire:
- High Ductility: Allows the wire to be deformed without cracking.
- Tight Tolerances: Essential for forming precise fastener shapes.
- Clean Surface Finish: Often coated with phosphate, lime, or other lubricants for smoother heading.
- Consistent Mechanical Properties: For uniform forming behavior.
- Good Cold Workability: The wire must maintain strength while being plastically deformed.
Common Grades Used
- Grade Type Application Notes
- C1006 Low Carbon Steel Good formability, used for small parts
- C1010 Low Carbon Steel General-purpose fasteners
- C1022 Medium-Low Carbon Steel Ideal for self-tapping screws
- C1038 Medium Carbon Steel More strength, less ductile
- 10B21 Boron Alloy Steel Good hardenability for heat-treated parts
- 4037 Alloy Steel High strength & toughness
Industries That Use It
- Automotive (engine and body fasteners)
- Construction (anchors and bolts)
- Electronics (tiny screws and pins)
- Aerospace (specialized fasteners)
- General manufacturing
Cold Heading Process Overview
- Wire Drawing: Steel is drawn into precise diameters.
- Surface Treatment: To enhance lubricity and remove oxides.
- Cold Heading/Forming: Wire is cut and shaped using dies at high speed.
- Secondary Operations (if needed): Heat treating, thread rolling, coating.
