DIN EN ISO 10683 applies with regard to non-electrolytically applied zinc flake coatings. DIN EN ISO 10684 applies with regard to hot-dip galvani
36、zing. DIN 267-2 applies with regard to surface roughness. Additional requirements and alternative surface conditions or finishing are to be agreed between manufacturer and purchaser.

37、es with regard to limit values for surface discontinuities. Acceptance inspection DIN EN ISO 3269 applies with regard to acceptance inspection. aWhere an electroplated coating as specified in DIN EN ISO 4042 is to be applied, depending on the coating thickness required, it may be necessary, particul
38、arly in the case of tolerance class 6H nuts, to select a larger fundamental deviation than that assigned to the H position. This however, might impair the resistance of the bolt/nut assembly to stripping. bWhere nuts are to be made to comply with other property classes, these shall be selected based
39、 on the relevant standards. cAs a departure from DIN EN ISO 898-2, a minimum hardness of 272 HV 30 will be adequate for fine pitch thread nuts assigned to property classes 8 and 10. dCU2 or CU3, at the manufacturers discretion.
