These are 6 X 1/2 custom painted sheet metal screws that we had painted for our architectural design customer to match their custom paneling. The darker color on the left is mixed to match the RAL 1019 brown while the lighter color on the right is formulated to match RAL 1015. Both color screws were finished with satin sheen clear coat to create the more matte finish desired by our customer and required by their finish samples provided. We typically run parts like this in bulk quantities and the lead time for the paint process is 3-4 weeks.
We had these custom black aluminum spacers manufactured for an automotive research facility using 6061-T6 aluminum material with black anodize finish. The inside diameter measures 5.3MM and the outside diameter 13MM. The overall length is 80MM and tolerance on all dimensions is +/- .10MM. Production was done domestically with a relatively quick turnaround time of 4 weeks including the anodizing process.
