Plating SS Screws with brass
I have a cottage business (www.basscapos.com). I use a truss-head 18-8
SS screw with the project, and spraypaint it gold to try to match the brass part it fastens. This is weak, I know, but I just can't find any gold-colored screw that is suitable, and strength is an issue. Does anyone know of a plating shop that would be well suited to doing a run of like 500 pieces? Robobass |

Also, bronze I can maybe see (I'm no metallurgist), but is there really any brass alloy that is close to 18-8 SS in strength? That flies in the face of my instincts and experience! Maybe I'm wrong...

Look here- http://www.caswellplating.com/kits/index.html and you might find something you can plate your SS screws with to match your needs Caswell's stuff is very good, but I think you could have 500 small parts plated for less than it would cost to set up to do it. Brush plating would be inexpensive, but brush-plating 500 parts would be quite tedious. The appeal to Caswell's stuff is that once set up, one-off small jobs cost almost nothing while taking anything, even one bolt, to a plating shop costs a job minimum that is never less than $50 and usually more like $100. I'm still using Caswell stuff I bought more than 5 years ago and have used many times. I had two small jobs-in-a-bucket today: one zinc and one tin. The zinc job is a small steel weldment, the tin job is a copper electrical terminal. |

It is around 300 or 350F that bronze occurs IIRC.

I have read that the temper colours occur about 100C higher on stainless steel so some trials might be required and an accurate temperature controlled furnace would help.

Robobass If you need strength, avoid 6-32 screws. This thread is bad because too much of the diameter of the screw is lost with such a course thread. Have you considered plating the parts yourself?

Zinc chromate typically goes on zinc, not on stainless. If the screws in question are available as bright zinc on steel, it's very easy to chromate them so they look a lot like brass. It's just a dunk in some juice for a few minutes. The juice is available from Caswell. 6-32 x 3/4 zinc-plated truss head screws are available from http://www.boltdepot.com/product.asp...26&cm=7&cd=393 |
Plating SS Screws with brass
Sorry I was unclear. The screw is a truss head sheet metal screw #6 x
3/4" 18-8ss. I've been searching a long time, and never found it in gold color. I will try the heat idea. I've got a butane mini torch. But, won't it loose strength if I heat it that much? It really needs to be fairly strong. I did have a plating rig years ago. Maybe I'll get another one. Trouble is, I'm in Germany now. You can't just go out and buy toxic chemicals the way you can in the US. (I bet it's getting harder there too. I've heard of high school science teachers being arrested for trying to order stuff to do classroom experiments that they had been doing for decades!) Robobass |
