注(1)：s(至大)的1欄適用于強(qiáng)度8.8及10.9及性狀A(yù)2-50、A2-70的內(nèi)容，2欄適用于強(qiáng)度12.9的內(nèi)容。但根據(jù)雙方當(dāng)事人之間協(xié)議，強(qiáng)度12.9的內(nèi)容也可以適用1欄。
螺紋的公稱直徑M20以上的s(至大)適用于所有的強(qiáng)度及性狀內(nèi)容。
注(2)：螺紋的公稱直徑中帶括號的盡量不要使用。
備注：1.頭部的側(cè)面帶有直紋或網(wǎng)紋[參照J(rèn)IS B 0951(滾花)]。此時，dk(至大)為該表中的帶**的數(shù)值。
此外，需要沒有滾花的貨時，訂貨人必須指定。但該dk(至大)為該表中帶*的數(shù)值。
2.對于螺紋的公稱直徑建議使用的公稱長度(?)為粗線框內(nèi)的內(nèi)容。
如果?比虛線位置短的為全螺紋，桿部的不完全螺紋長度約為3P。
3.公稱長度(?)比虛線位置長的話，?g(至大)及?s(至小)根據(jù)下式?jīng)Q定。
?g(至大)=公稱長度(?)-b
?s(至小)=?g(至大)-5P
