①,若以小數(shù)規(guī)定公稱直徑，應(yīng)省略小數(shù)前和小數(shù)點(diǎn)后第四位的零。
②,螺釘末端釘尖上不允許因螺紋輾壓而形成的虛尖，允許略帶圓弧或圓鈍形末端。
③,小于等于8#的螺釘，螺紋牙頂平面寬度不應(yīng)超過0.004in，大于8#的應(yīng)不超過0.006in。
④,正常情況下，當(dāng)螺釘長度小于等于其公稱長度L0時(shí)應(yīng)采用全螺紋，過渡螺紋長度應(yīng)小于等于Y；若螺釘長度大于其公稱長度L0可采用半牙型式，但其螺紋長度應(yīng)不小于b。

長度公差

　　Tapping screws can be made to any length, but they are generally produced in fractional length increments of 1/16 in. for screws up to 1/2 in. long, 1/8 in. for screws over 1/2 in. through 1-1/2 in. long, 1/4 in. for screws over 1-1/2 in. through 3 in. long, and 1/2 in. for screws over 3 in. long.
