QB/T2209--1996
This standard is revised based on the Ministry of Light Industry of the People's Republic of China Standard SG217-1980 "Assorted Hammers". According to the actual needs of the product, this standard changes the wide and narrow screw rods in the original standard assorted hammer accessories to slotted screw rods and cross-slot screw rods.
This standard changes the hardness of the screw rod in Article 4 of the original standard technical conditions from HRC45~50 to HRC48~54. This standard adds Article 4.5 on the assembly requirements of accessories and handles, and Article 4.6 on the connection requirements of hammer heads, handles, side hole screws, and back cover threads, replacing the original standard thread accuracy and the matching tolerance of accessories and handle holes. From the date of implementation, this standard will also replace SG217-1980. This standard is proposed by the Quality Standards Department of the China Light Industry Federation. This standard is under the jurisdiction of the National Tool Hardware Standardization Center. The drafting units of this standard are: Shanghai Tool Industry Research Institute, Shanghai Qianjin Machinery Factory. The main drafters of this standard are: Lu Xialing and Xu Haiwen. 575
