Kester 24-6040-0053 Solder Roll, 66 Core Size, 0.050 Diameter

its solder.....

The best thickness for 95% of the work. I am an engineer, certified for soldered connection on maned space flight. By this solder.

Works for me.

Works Great

Its been around for ever. Ive been using it since the mid 1960s, and it performs just as well today. Great stuff

Good price

Its rosin core 60/40 solder. it melts, sticks to wires and goes solid again and there is enough here to cover my needs for the next decade or so. What more can you ask of solder.

So much better than the off-brand that I bought. No comparison.

Highly recommend this product!

just needed to stock up - Ive been using Kester solder since the 50s restoring old tube radios
