Wire for Screws & Rivets
Grade selection guide for screw and rivet production — covering formability, strength, and condition for common CHQ wire grades.
Screws and rivets are among the most common cold-headed fasteners in the world, used in everything from electronics assembly to structural construction. The wire that feeds these forming operations needs to be consistent — in chemistry, in surface, in dimensional tolerance — because any variation translates directly into headed-part quality and machine downtime.
Grades we commonly stock for screws and rivets
C1006 — soft, easy-to-form low-carbon wire. Ideal for small rivets and sheet-metal screws where formability matters more than strength.
C1010 — slightly higher carbon. A workhorse for general-purpose screws, machine screws, and standard rivets.
C1018 — when customers need a touch more strength and machinability. Available as special order.
C1022 — boron-treated low-carbon, used where modest heat-treat response is needed. Common in self-tapping screws.
10B21 — boron alloy, the go-to for self-drilling screws and applications requiring through-hardening.
Condition
Most screw and rivet wire is supplied SAFS (spheroidize annealed, finely drawn). For specific applications with higher draw requirements, SAIP is available. See the SAFS vs SAIP guide for detail.
