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
