27       Soluble Oil Dipped Ferrous parts (except stainless steel) have a light coating of soluble oil applied. Non-ferrous parts are cleaned where necessary and are left in plain condition. Natural Low-Cost finish, recommended on ferrous parts for conditions of relatively little corrosion or for parts that are to receive a finish in the customers' plants 5% solution at 95 degrees Fahrenheit. Ferrous parts: first rust spots after 1 hour, end point (1/16" dia. rust spots) after 2-1/2 hours. Nonferrous parts: corrosion will be normal for plain finish of the material.
4 ESB-M3P4-A, ESS-MP20-A GM4435 Code A PS80 Plus Oil Phosphate and Oil Parts are phosphate coated, then dipped in a special oil and spun dry Black Moderate corrosion resistance. Neat in appearance -will not wear off in handling. 5% solution at 95 degrees Fahrenheit. First rust spots after 32 hours. End point (1/16" dia. rust spots) after 48 hours.
1   GM4435 Code B PS80, PS85 Phosphate Coated, then Two Coats Olive Drab Paint are applied. Each coat is properly baked to obtain maximum protection. Olive drab. Good corrosion resistance. Does not cause hydrogen embrittlement common with electroplated high carbon spring steel. Excellent for insulating dissimilar metals against electrolytic action. 5% solution at 95 degrees Fahrenheit. First rust spots after 48 hours. End point (1/16" dia. rust spots) after 96 hours.
67   GM4435 Code (093)   Parts are phosphate coated, and then two coats of aluminum paint are applied. Each coat is properly baked to insure maximum protection. Aluminum color- smooth appearance Recommended in place of cadmium plating where appearance and corrosion resistance are requirements. High in abrasion resistance and a non-conductor of electricity. 5% solution at 95 degrees Fahrenheit. First rust spots after 48 hours. End point (1/16" dia. rust spots) after 96 hours.
963 ESAM21P2-A4, WSDM21, P13-A2, A3, WSDM21P11-B1 (S301 for Non-threaded parts) GM6173M PS5873 Water Based zinc coating Dacromat 320 or equivalent plus clear sealer Parts are coated in a water based zinc coating for maximum protection. Grey metallic. Exceptional corrosion resistance. Does not cause hydrogen embrittlement 5% solution at 95 degrees Fahrenheit. End point (1/16" rust spots) after 400 hours.
NOTE: The following electroplate finishes are limited to only a few parts, such as Tubular Type clips and Tube Clamps. Please do not specify these finishes for other types of Tinnerman Palnut fasteners without the approval of our engineering department.
