Vrooom666 31 Posted September 1, 2015 Why tamiya has turned over to brown screws now? they used be silver, then "rainbow" coloured.... now brown screws.. My latest M-05 and DT-03 has brown screws... but my lunchbox few years ago has silver colours.. why the change ? Share this post Link to post Share on other sites
volvotech 101 Posted September 2, 2015 Good question. I was actually happy to see that olive brown finish screw in my dt03. Reminded me of the ta03 kits I built when I first got into the hobby. Share this post Link to post Share on other sites

berman 5315 Posted September 2, 2015 Brown screws are less invasive than silver screws. Rather the car look like a model than a meccano set Share this post Link to post Share on other sites

The real truth is that I phoned to Mr. Tamiya pointing out that coloured screws offend my aesthetic feeling. He agreed with me and he made me happy phoning to the production asking to ALL Tamiya employees to paint the huge stocks of screws with markers. 2 Share this post Link to post Share on other sites

But please, markers not hallowed, thanks! Share this post Link to post Share on other sites
oz-trash-cowboy 63 Posted September 2, 2015 Cost / Batch ratio most probably. Some of the steel screws used in early tamiya were yellow / gold looking type colour. The steel plating process (passivation) contained cadmium and zinc. Cadmium is no longer considered a consumer friendly substance. Modern(?) material processing science has provided alternatives. Its is possible to plate steel, green, brown, black, yellow, etc. The silver looking plated screws are treated / passivated with a clear zinc, not to be confused with hot zinc dipping or galvanising, rather a chemical reaction from solution onto the steel surface. The protective layer is micron thin and if you have run your car at the beach, you will most likly agree the corrosion resistence is low. 1 Share this post Link to post Share on other sites
