5
Tightest Fit
最緊匹配
MMC (female) – MMC (male) = TF
MMC（母件）－ MMC（公件）＝ TF
Smallest Hole – Biggest Shaft = TF
最小孔－最大軸＝ TF
Minus

=
TF
6
Loosest Fit
最松匹配
LMC (female) – LMC (male) = LF
LMC（母件）－ LMC（公件）＝ TF
Biggest Hole – Smallest Shaft = LF
最大孔－最小軸＝ TF

=
LF
7
Clearance Fit
間隙匹配
在所有公差情況下的間隙，TF和 LF總為＋
MMC（母件）－ MMC（公件）＝ TF
最小孔－最大軸＝ TF
LMC（母件）－LMC（公件）=LF
最大孔－最小軸＝LF

8
Interference Fit
障礙匹配
在所有公差情況下的障礙，TF和 LF總為－
MMC（母件）－ MMC（公件）＝ TF
最小孔－最大軸＝ TF
LMC（母件）－LMC（公件）=LF
最大孔－最小軸＝LF

9
Transition Fit
過渡匹配
有時間隙，有時障礙，TF和LF可能為＋或－
MMC（母件）－ MMC（公件）＝ TF
最小孔－最大軸＝ TF
LMC（母件）－LMC（公件）=LF
最大孔－最小軸＝LF
