35、tional Standard specifies material, process, dimensional and some performance requirements for hot dip spun galvanized coatings applied to coarse threaded steel fasteners from M8 up to and including M64 and for property classes up to and including 10.9 for bolts, screws and studs and 12 for nuts. It
36、 is not recommended to hot dip galvanize threaded fasteners in diameters smaller than M8 and/or with pitches below 1,25 mm. NOTE Attention is drawn to the fact that the proof loads and stresses under proof load of oversize tapped nuts with threads M8 and M10 and the ultimate tensile loads and proof
37、loads of undersize threaded bolts and screws with threads M8 and M10 are reduced as compared to the values specified in ISO 898-2 and ISO 898-1 respectively and are specified in Annex A. It primarily concerns the spun hot dip galvanizing of threaded steel fasteners, but it may also be applied to oth
38、er threaded steel parts. The specifications given in this International Standard may also be applied to non-threaded steel parts such as washers. 2 Normative references The following referenced documents are indispensable for the application of this document.
