The wire must be free from harmful flaws like seams, cracks, or rust that could lead to fastener failure. Tolerances on diameter and ovality are stringent, typically specified in the standard (e.g., as discussed in related JIS G3539 documentation) to ensure the wire fits correctly into automatic headers.

Scale is removed via acid pickling, followed by phosphate coating to lubricate the wire during drawing.
Used for high-strength bolts and automotive components that undergo subsequent heat treatment (quenching and tempering). 2. Chemical Composition

The standard was first published by the Japanese Standards Association (JSA) and is now superseded. As of its last official edition, the document consisted of 10 pages and was available in both Japanese and English.
Generally used for moderate strength fasteners.
Often used for high-tensile bolts requiring subsequent heat treatment. Common Applications (SWCH Grades)
JIS G3539 is distinct from other Japanese steel standards, though it is often mentioned alongside them. The table below highlights the key differences: The wire must be free from harmful flaws
JIS G3539 is a standard that covers steel wires used for cold heading and cold extruding, which are processes used to manufacture fasteners, such as bolts, nuts, and rivets. The standard specifies the requirements for the chemical composition, mechanical properties, and microstructure of steel wires used for these applications. The standard also provides guidelines for the testing and inspection of steel wires to ensure that they meet the required specifications.

When cross-referencing JIS G3539 within international engineering projects, manufacturers frequently map it to the following global specifications: JIS Standard ASTM (USA) Equivalent EN (Europe) Equivalent ISO Equivalent ASTM A545 / A510 EN 10263-2 / EN 10263-4
