Kester part number 24-6337-9756 is a professional grade solder wire featuring a Sn63Pb37 eutectic alloy composition with 285 Rosin Activated flux at 3.3% core density. The 0.010 inch diameter makes it ideal for precision work on small components, PCB assembly, fine electronics rework, and detailed through hole soldering where control and accuracy matter. This thin profile delivers reliable wetting and joint quality while the rosin flux minimizes oxidation during the soldering process. A trusted choice for technicians and repair professionals who demand consistent performance and American made reliability.
