10B21 boron steel wire is described for cold heading bolts, automotive fasteners and industrial parts. Confirm the actual wire grade and form before choosing material for a forming process.

• 10B21 is the stated grade.
• Boron Steel is the steel-grade description.
• Drawn Wire is the stated product type.
• The diameter description is 5.5-16.0mm.
• ASTM A510 is a reference to verify.

Specify the cold heading material

Request the offered 10B21 composition and condition for the intended fastener. Other broad material references should not be treated as equivalent grades for a high-strength bolt requirement.

Confirm wire form and surface

The technical description also uses wire-rope and galvanized-surface terminology. Clarify the actual drawn-wire form and surface condition needed for cold heading rather than assuming a rope or construction-wire supply.

Match the fastener process requirements

State the required diameter and forming route for the 10B21 enquiry. Obtain applicable ASTM A510 and material evidence; the finished bolt properties cannot be inferred from the wire grade alone.
