Precision Brand 21125 Tempered Music Wire Coil 38 Gauge

Product Description

The PRECISION BRAND 21125 is a tempered high carbon steel music wire coil conforming to ASTM A228 standards. Measuring 0.125 inches in diameter and 24 feet in length at 38 gauge, this wire is drawn and heat-treated to deliver consistent tensile strength and spring-like elasticity. It is used across industrial, mechanical, and trade applications where precision wire stock is required. Machinists, tool and die fabricators, and maintenance technicians typically work with this material for custom spring fabrication, pin stock, and mechanical assemblies requiring tight dimensional tolerances.

This wire coil is suited for shop and field use wherever a reliable, pre-tempered wire stock is needed. The ASTM A228 designation confirms the wire meets established mechanical property requirements for high carbon steel music wire, making it appropriate for both prototype work and production-level applications. The 24-foot coil length provides useful working stock for bench fabrication tasks without excess bulk.

Key Features

• High carbon steel construction tempered to ASTM A228 specification for consistent mechanical properties
• 0.125 inch diameter at 38 gauge provides accurate, uniform cross-section throughout the coil
• 24-foot coil length offers substantial working stock for custom fabrication tasks
• Pre-tempered finish eliminates the need for additional heat treatment before use
• UNSPSC Code 31152200 for streamlined procurement classification

Compatibility

Designed as a general-purpose tempered music wire coil suitable for mechanical fabrication, spring-making, and precision wire stock applications where ASTM A228 high carbon steel wire is specified.

Installation Notes

Work with appropriate personal protective equipment including cut-resistant gloves when handling and cutting wire stock. Use proper wire-cutting tools rated for high carbon steel to ensure clean cuts and prevent tool damage. Secure the coil when unspooling to prevent recoil injury. No electrical shutoff is required for this mechanical material, but standard shop safety practices apply when using cutting or bending equipment.
