Precision Brand 21231 Music Wire 0.031 in Round 1/4 Lb Coil

Product Description

The PRECISION BRAND 21231 is a round music wire made from a high carbon steel alloy and sold in a 1/4 lb coil. The wire measures 0.031 inches in diameter with a tolerance of plus or minus 0.0004 inches, yielding approximately 390 feet per pound. Spring tempered during manufacturing, it delivers high tensile strength and high fatigue resistance, making it a reliable choice for precision fabrication and industrial maintenance applications. Machinists, fabricators, and maintenance technicians work with this wire across a wide range of light industrial and mechanical tasks.

This music wire is suited for both shop and field use wherever a consistent, high-strength round wire stock is required. Common applications include fabricating springs, bending wire forms, routing control linkages, securing armature binding, and cutting ceramics. It is also used in a broad variety of general industrial applications where dimensional consistency and material strength are critical. The 1/4 lb coil size is practical for bench stock or low-volume production runs.

Key Features

• 0.031 inch wire diameter with a tight tolerance of plus or minus 0.0004 inches for consistent fitment in precision applications
• Spring tempered high carbon steel alloy construction for high tensile strength and fatigue resistance
• Approximately 390 feet per pound, providing a known length reference for planning and cutting
• Round cross-section suitable for springs, wire forms, control linkages, and armature binding
• Available in a 1/4 lb coil for manageable bench stock quantities
• Suitable for ceramic cutting and a broad range of industrial fabrication uses

Compatibility

Designed as a general-purpose round music wire stock for industrial, mechanical, and fabrication applications requiring a spring-tempered high carbon steel wire at 0.031 inches in diameter.

Installation Notes

Music wire is typically handled by machinists, fabricators, or maintenance technicians using standard wire-cutting and bending tools appropriate for hardened high carbon steel. Wear appropriate hand and eye protection when cutting or forming spring-tempered wire, as cut ends can be sharp and wire under tension can spring back unexpectedly. Measure and cut in a controlled manner to avoid kinking, which can compromise tensile strength at the bend point.
