国标自攻螺丝详细尺寸表

1、国标自攻螺丝详尽尺寸表国标自攻螺丝详尽尺寸表国标自攻螺丝详尽尺寸表国家标准螺丝规格表，螺丝牙距规格表我们螺丝行业的螺丝生产厂家，在生产制造中间，销售过程中间，服务客户过程中间，碰到客户问，什么样的螺丝规格是什么，它们的螺纹牙距是多少？那么假如有一个螺丝规格表，把螺丝螺纹牙距，螺丝种类，螺丝各方面基本信息都用一个图表来表示，清楚，了然，简单易懂。那么使用起来就方便多了。下边深圳市创固螺丝朱经理，把螺丝规格表，把螺丝螺纹牙距规格表显上，供大家方便使用，查问。螺丝规格表a.Slotted:一字(Minus)b.Phillips:十字(Plus)c.Phil-Slot:一字/十字d.HexScoket
