(a) This Standard covers the complete dimensional and general data for metric series heavy hex flange screws recognized as American National Standard. (b) The inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Consumers should consult with suppliers concerning availability of products. 2 COMPARISON WITH ISO/DIS 8102 (a) Heavy hex flange screws as presented in this standard are harmonized to the extent possible with the draft international standard ISO/DIS 8102, Hexagon Bolts With Flange- Heavy Series, and with revisions agreed to by ISO/TC2/WG2 in May 1989 in Zurich and later that have not been published in a revised draft. If it were published, the dimensional differences between this Standard and ISO/DIS 8102 would be few, relatively minor, and none would affect functional interchangeability of screws manufactured to the require- ments of either. This Standard specifes some requirements that are not included in ISO/DIS 8102. Dimensional requirements shown in bold type are in addition to, or differ from, ISO/DIS 8102. The technical differences between this standard and the ISO documents are described in Appendix A. (b) Letter symbols designating dimensional charac- teristics are in accord with ISO 225, Fasteners- Bolts, Screws, Studs and Nuts Symbols and Designations of Dimensions, and with ISO/DIS 8102, except where capitals have been used instead of lowercase letters used in the ISO standards. 3 REFERENCED STANDARDS The following is a list of publications referenced in this Standard.
