①,若以小數規定公稱直徑，應省略小數前和小數點後第四位的零。
②,方槽内壁略帶錐度，以保證插入深量規與有鍍層螺釘凹槽的配合。為使插入深測量深度适用于有塗鍍層的螺釘，制造者在生產（镦頭）時，應為其留出必要的加工餘量。
③,表中的“R”表示正常插入深入。
④,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。
⑤,小于等于8#的螺釘，螺紋牙頂平面寬度不應超過0.004in，大于8#的應不超過0.006in。
⑥,正常情況下，當螺釘長度小于等于其公稱長度L0時應采用全螺紋，過渡螺紋長度應小于等于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.

類型	标稱螺釘長度	長度公差
A、AB、BP	≤1	±0.03
A、AB、BP	＞1	±0.05
B、BF、BT、C、D、F、G、T、TRS	≤3/4	-0.03
	＞3/4,≤1-1/2	-0.05
	＞1-1/2	-0.06
