Product Overview
Cold-forged screws are fasteners produced through the cold forging process and are commonly used in mechanical equipment assembly, automotive component connection, and structural anchoring.
product advantages
Precision Dimensions
Cold-forged screws are formed using high-precision dies with dimensional tolerances of ±0.02 mm, ensuring a tight fit with the nut.
High Strength
Cold-forged screws are formed at room temperature using high-pressure equipment, achieving a tensile strength of 900–1200 MPa, which ensures they are not prone to fracture under high load conditions.
Multiple Specifications
Cold-forged screws are available in a variety of head styles, including pan, flat, and hexagonal heads, with sizes ranging from M3 to M20 and available in both metric and imperial specifications.
High Corrosion Resistance
The screws can be treated with zinc plating, nickel plating, or Dacromet coating, forming a protective film on the surface that blocks moisture and air, extending their service life to 8–10 years.
Quality Assurance
In-Process Inspection
Screw dimensions, surface finish, and mechanical properties are inspected during key processes such as cold forging, tapping, and heat treatment, and defective products are promptly rejected.
Final Testing
Tensile strength, hardness, and corrosion resistance tests are performed before packaging to confirm that the screws meet performance standards.
