Anodizing on Threads

October 11, 2016

Q. Is there a maximum thickness anybody can recommend for anodizing components with threads?
I was proposing to stipulate 10-15 µm max.

Anodizing will be Type II Non dyed to Mil-A-8625 [link is to free spec at Defense Logistics Agency, dla.mil] F which only leaves the thickness open to 1.8 - 25.4 µm.

Any Help is welcomed.

A. Hi Richard. Helicoil threaded inserts after anodizing are certainly a better way to go if possible. Some very knowledgable people say that threads should never be anodized at all. See letters 41102 and 19641 for more. Good luck.

Apologies for the delays. Finishing.com has as much traffic today as back when we had 5 employees -- but changing times mean we only have the income to support one guy who is doing his best to keep up :-)

I see two submittals from you; the other one, posted on letter 45267, appears to have been submitted under a fictitious name. You can help yourself by using the custom search engine, because almost every topic, including this one, has been addressed multiple times before.
