K-T Industries rosin-core solder wire, 40/60 tin-lead alloy, supplied as a 1/4 lb spool. The 3/32" diameter is well-matched to chassis wiring, terminal lugs, and general electronics work. The 1/4 lb spool is a good fit for occasional repairs and small project boxes.

• Alloy: 40/60 tin-lead with rosin flux core
• Wire diameter: 3/32"
• Spool weight: 1/4 lb
• Pre-fluxed - no separate flux required for clean copper
• Suitable for electrical splices, terminal lugs, switches, and general electronic projects

Tip: Lead-bearing solder. Work in a ventilated area, do not eat or drink at the bench, and wash hands after handling. Step down to the 1/16" diameter spool for fine PCB and component-lead work.
