| Surface color silver (ZNS): Applicable only for shaft screws with metric regular and fine threads as per DIN 13-28 and nuts with nut heights of 0.8 x d as per DIN 934 and solely for a spread of μ = 0.09 to 0.15 (cadmium-coated screws, nuts without post-treatment or galvanized.) Lubrication status: Both un-lubricated and oiled). The values specified in the table apply to a screw/screw connection in accordance with the above-mentioned conditions.
