Would you please tell me the specifications and specific sizes of the plum screw driver?
Should be T30, the standard T30 head, plum diameter is 5.52mm, your 5.50 is the closest, and basically is it, than T30 up to a specification is T27, is 4.99mm, the difference is a bit big, should be T30
But if it is with T type screwdriver in that case, the size of that must be T6 T10, 6,10 is expressed in head size... I just do a screwdriver, six cents, is S, S1 is 5MM thick, S2 6MM, S3 8MM.5.5 is the special... .
You just said a diameter, screwdriver specifications in general, word cross is like this, how long X how much rough, such as 100MM long, 5MM thick, 100MM=4 inches, is 4, *5, or 5*100MM, you say, I do not know what kind of plum
