We are in the marine industry and are introducing a new product. Last year we have sold over 900 products/anchors.  Enclosed are drawings, images and 3D CAD files of the part - anchor shank that should be cast, with the high precision in the 17-4PH stainless steel (H900 heat treatment). Surface finish should be high quality mirror/mirror hand polished surface. The part is ≈ 0.600kg. The Shank must have a perfect surface finish with no scratches, small holes and up-down/hill waves imperfections. The bottom surface with two (2) 3/8"-16 threaded holes must be grounded perpendicular and be perfectly flat! The two 3/8”-16 threaded screw holes must have clean threads so that the screws could be screwed in/out easily with fingers. The distance of 23mm between center holes must be done with a high precision. Depth of the 3/8”-16  threaded holes should be 18mm minimum. Basic dimensions are in mm.
