螺纹的公称直径M20以上的s(最大)适用于所有的强度及性状内容。
注(2):螺纹的公称直径中带括号的尽量不要使用。
备注:1.头部的侧面带有直纹或网纹[参照JIS B 0951(滚花)]。此时,dk(最大)为该表中的带**的数值。
此外,需要没有滚花的货时,订货人必须指定。但该dk(最大)为该表中带*的数值。
2.对于螺纹的公称直径建议使用的公称长度(ℓ)为粗线框内的内容。
如果ℓ比虚线位置短的为全螺纹,杆部的不完全螺纹长度约为3P。
3.公称长度(ℓ)比虚线位置长的话,ℓg(最大)及ℓs(最小)根据下式决定。
ℓg(最大)=公称长度(ℓ)-b
ℓs(最小)=ℓg(最大)-5P
2.内六角螺栓的L和ℓs及ℓg
