Set the fastener-wire grade

Choose10B21 or10B33 and obtain the applicable composition and condition. Other carbon-steel grade references should not be combined into one coil specification.

• Cold Heading Steel is the special use.
• 10B21 and10B33 are grade references.
• Polished surface is described.
• Cutting service is named.
• Bolts, nuts and screws are intended uses.

Confirm rod form and diameter tolerance

Request drawn wire or rod in the form needed by the production equipment. Clarify the isolated wire-rope wording and what the stated±1% tolerance measures before acceptance.

Agree processing and standards evidence

Cold-rolled and hot-rolled descriptions require a chosen delivery condition. Ask for the actual material standard and relevant ASTM or SAE records rather than treating both labels as confirmed compliance.
