M3*0.5是螺牙(or螺纹)规格描述,M是公制螺牙(or螺纹),3是螺牙(or螺纹)外径,0.5是牙距Pitch值,国标中常用的M3螺牙(or螺纹)是0.5的Pitch,书写时略写; M3*6H是螺牙(or螺纹)规格+螺牙(or螺纹)的精度等级描述,M3同上说明。6H精度等级,还有7H精度等级,是设计图面要求的。 00分享举报您可能感兴趣的内容广告...
M3*0.5是螺牙(or螺纹)规格描述，M是公制螺牙(or螺纹)，3是螺牙(or螺纹)外径，0.5是牙距Pitch值，国标中常用的M3螺牙(or螺纹)是0.5的Pitch，书写时略写；M3*6H是螺牙(or螺纹)规格+螺牙(or螺纹)的精度等级描述，M3同上说明。6H精度等级，还有7H精度等级，是设计图面要求的。
1、 与你所用的丝锥螺距有关,M3一般常用2.5MM；M4和一般常用3.3MM; M5一般常用4.2MM; M6一般常用5MM; M8 一般常用7MM。2、螺距：沿螺旋线方向量得的，相邻两螺纹之间的距离。一般指在螺纹螺距中螺纹上相邻两牙在中径线上对应两点间的轴向距离。
