K-T Industries rosin-core solder wire, 40/60 tin-lead alloy, supplied as a 1/4 lb spool in the fine 1/16" diameter. The thin wire feeds precisely into small joints, making it the right pick for printed-circuit work, component leads, and fine electronic assembly.

• Alloy: 40/60 tin-lead with rosin flux core
• Wire diameter: 1/16" (the finest of the K-T rosin-core lineup)
• Spool weight: 1/4 lb
• Pre-fluxed - no separate flux required for clean copper
• Use for printed-circuit board work, small component leads, and other fine electronics

Tip: Lead-bearing solder. Work in a ventilated area, do not eat or drink at the bench, and wash hands after handling. Step up to the 3/32" or 1/8" spool for chassis wiring, terminal lugs, and other larger-gauge joints.
