A precision 3mm diameter shaft x 60mm suitable for many of our plastic gears, sprockets, model bearings and model wheels. This steel shaft is, we believe, silver steel and has ground ends making it ready for use.
The shaft is steel, you cannot solder steel easily if at all. You braze steel with silver solder as an example.

Correction - it can be soldered!

Soldering steel with soft electrical solder is not recommended and is not easy plus the strength of the joint will be low. If you have managed to solder steel in this way and you are happy with the results then great but we would not recommend this method to others. Really for steel you need to braze but if you wish to soft solder, then use an acid based flux rather than the resin you find in cored solder used for electronics use.

Yes, it works just dandily! It only has about 550 grammes of load on it at any one time, so that can be a referable parameter. Phill.

Thank you for the feedback, I am wondering whether the Zinc plating has made is easier rather than bare steel?

I don't rightly know, sir/madam! But since you've asked, i did a little experiment with it and i had to push quite hard to break a brass screw off the shaft after soldering it, at a very unscientific and extremely rough guess, about 3 or 4 kilos of pressure. The solder in fact had completely come off the brass piece but was still adhered to the shaft, proving your point that solder itself isn't terribly strong, but the shaft itself can at least take it. I wouldn't recommend it either, as it's not that strong but it worked for my very rudimentary needs. If you need any more advice, don't hesitate to contact me. LOL. Phill.
