The special gauges for hexagonal flower size in this standard adopt the provisions recommended by the draft standard of ISO/TC29/SC10N261, and the hexagonal flower test holes for torque test also adopt the provisions recommended by the draft standard. This standard adds a total of ten specifications of hexagonal flower screwdrivers, T6~T27, T45~T50, and makes corresponding provisions. In order to adapt to the provisions of GB10635 and GB10636 that have been formulated, this standard adopts the relevant contents of the two standards. Appendix A and Appendix B of this standard are prompt appendices. This standard is proposed by the Quality Standards Department of China Light Industry General Association. This standard is under the jurisdiction of the National Tool Hardware Standardization Center. The drafting units of this standard: Shanghai Tool Industry Research Institute, Shanghai Changzheng Screwdriver Factory. The main drafters of this standard: Chen Chunli and Lu Xialing. 293
