垫圈. 交货技术条件 DIN 522 - 1990

        This standard specifies requirements for metal washers manufactured by stamping (punching) which thus exhibit inside and outside rollover and fracture (cf. DIN 6930 Part 2 and DIN 6932). it does not cover washers manufactured by machining (e.g. by drilling or turning).

        本标准规定了垫圈的公差和极限偏差，垫圈的首选应用是螺栓/螺母组件。这些公差将用于处理F、A和C级产品垫圈的标准，这些垫圈专为公称螺纹直径为1~160mm的螺栓、螺钉和螺母设计。
