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。“S”表示短（淺）插入深度。
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。
