7075T651 is very strong aluminum. There is over 1.00 of complete thread. I have used the one on my site for about 10 years and the bolts and threads in the fixture are still like new. The keyway is made from .625 DIA 304 stainless steel. Socket head cap screws are class 3 A threads-alloy steel heat treated.

Steel washers are gold zink coated. Anodize is hard black NI-acetate seal. Thickness is .002 -- .001 penetrates into aluminum so it will not flake or peal off. Threaded holes and .501 dowel pin holes were masked for anodize. The hog out on the fixture was ruffed with a 1.000 DIA 3 flut ruffer. 7000 RPM 1.8 deep .3 step over at 50 IMP. I could have gone faster but I ran out of horse power.
