SAE10B21 and10B33 polished steel wire rod is described for cold heading, nail making and fastener production. A stated1–10mm diameter range provides a starting point for a dimensioned inquiry rather than separate confirmed size variants.

Choose the cold-heading steel grade

Specify10B21 or10B33 and request the composition and material condition for the offer. Other grade-family references do not establish that one supplied coil meets every named grade.

• Steel wire rod is the product form.
• 10B21 and10B33 are principal grade references.
• Polished surface is described.
• Cutting is an available processing reference.
• Cold heading is the stated special use.

Agree diameter and delivery condition

Requests for4mm,6.5mm or10mm need an actual diameter tolerance and supplied condition. Clarify whether cold-rolled, hot-rolled or drawn processing applies to the required wire.

Define the fastener production requirement

Bolts, nuts, screws and rivets are named uses. Request relevant SAE material evidence and confirm what the stated±1% tolerance measures before treating the wire as qualified for a particular forming process.
