Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

Works far better than the cheap stuff elsewhere.

I used the solder to connect a wire in a flashlight that had broke loose. The flashlight is working now.

Maybe my brain will fry, but I dont have good luck with lead free solder. 63/37 is at the lead-tin eutectic point and has the lowest melting point of good solders.

Have to have real solder to do the job

Was dubious of the 63/37 alloy (having grown up on 60/40) and the thin wire until using it. Flowed well and the thin wire required less heat. This is my new go to.

Been using this solder type for 50 years. EXCELLENT flow and boding. The flux is also easy to remove.

Excellent! Exact product I was looking for and Amazon has it at the best price and eligible for shipping. Have purchased multiple times and will continue to purchase from Amazon.

This is amazing. I was buying a cheap brand of solder before. It truly makes a difference to have a quality solder to work with.

I ordered some cheap solder and it cost more money due to the horrible solder job. I first thought it was me because Im a beginner. after trying Kester (recommended by You Tube video) my solder jobs look a whole lot better. Do yourself a solid and spend the money on GOOOOOD solder Kester is the best. I completely ruined my bullet connectors and had to buy new ones, money that could have been saved if only i purchased good quality solder.

On the stand it stands perfectly
