枫下家园 / 美丽家居 / 为什么这个带方口的Metric螺钉和 十字头的Metric 螺钉规格不一致呢?拧到一半就拧不进了,那个十字口的就可以,量了一下尺寸,方口的直径比十字口的牙的直径大了0.1mm 左右,以前还真不知道,方口的到底用什么标准?谢谢!

The size of screw has nothing to do whether it is 方口 or 十字。The only explanation is they are different size (or different thread specification).

But frox the label of the box,it is Metric Screws, so it supposed to match with a metric holes, but it isn't true when i use it to a metric M5 screw hole, well if I use a philip head screw on it, it works well. So I want to know, whether the screw has two standards for metal and wood, It looks like Square head screws, is most used at woodworking, even if the box label it machine screws.

M5 有粗牙和细牙。试试0.5的。

你怎么确定螺孔也是M5的?也许是英制的, 10-24, 10-32. 这两个和M5 太接近了, 有时候傻傻的分不清。。

这个螺孔图纸标注就是公制的, 螺纹的标注公制和英制大不相同,公制用M5 英制则用,1/4",1/2"标注孔径,木螺钉一般英制的都是, #2,#3,...#10x英寸的表法,而这个盒子上明显标识有METRIC 和M5X25, 典型公制标法。

希望螺丝能标准化!

判断两个螺丝是不是同一个规格,最简单的办法就是把他俩个叠在一起,看螺纹的匹配是不是严密。
