Source for 13 mm hex wrench

[Ameer Antar]

true, but there's only .03" difference. whether you're torquing down or 
loosening, your still putting the rated torque on the head. Your just 
putting torque more on one part of the flats or the other. There are some 
metric and english values that are pretty different, but 13mm and 1/2" are 
one of the closest. There's really no problem, unless your torquing down a 
piece of soft plastic w/ a 1/2" allen wrench. Even some manuals call for 
1/2" or 13mm wrench. I don't see any problem or damage resulting from that 
at all.
