A = 25 is applicable to BMFRA and BMFRAA only, and A = 60 to BMFRS only.
For thread diameter selection, specify 0, 5, 1, 2, 3, 4 or 6 indicated before ( ).
"For the purposes of improved standardization, the conventional A Dimension 60 has been changed to '60N.' The (a/b Dimension 8 mm) conventional standard (a/b Dimension 10 mm) is to be discontinued in September 2022."
