4 Dimensions and designation
4 尺寸和名稱
4.1 Standard coating
標準塗佈
Unless otherwi specified, the coating shall cover a zone, measured from the bolt end, of length equal to
除了另外制定情況外，塗料應該覆蓋整個區域，從螺栓底部開始測量，塗佈長度等於
1.5d±2P
The first two or three turns of thread shall be free from coating material to facilitate bolting (e Figure 1). Coating residue in the turns is permitted unless this adverly affects the specified function and/or u of the bolt.
螺紋的前面2~3牙應該不塗塗料，這樣便於旋入（見圖1）。殘留在原來螺栓上
的塗料可以被允許，除非它不利於指定的功能或者螺栓的使用。

4.2 Non-standard coating
非標準塗佈
If, for design reasons, a different length l b and/or a different distance a between the coating and the end of the bolt is required (e Figure 2), both dimensions shall be indicated in the standard designation (e 4.3). For dimension l b a tolerance equal to ± 2 P applies.
由於設計的原因，需要不同的塗佈長度和塗佈位置(見圖2)，這兩個參數應該在指定的標準上註明(見4.3)，尺寸公差等於±2個牙距。
