BS ISO 885:2000 pdf – General purpose bolts and screws Ð Metric series Ð Radii under the head.
Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISo shall not be held responsible for identifying any or all such patent rights. International Standard ISO 885 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 7, Reference Standards for fasteners (mainly covering terminology, dimensioning, sizes and tolerancing). This second edition cancels and replaces the first edition (ISO 885:1976), which has been technically revised.
1 Scope This International Standard specifies the sizes of the radii under the head and the transition diameters of metric series general purpose bolts and screws. 2 Dimensions See Figure 1 and Table 1.
