7/32"
That's so close to 5.5 that a 5.5 key would've fit. Ain't but a couple thousandths difference.
If the socket is between 5 and 5.5 it's probably 13/64". A rare size but not totally unheard of.

the reason i ask is that i bought a troy bilt weed-eater and has the push to start option that i dont plan to buy as it is 40 bucks but it is a hex key on a electric motor so i thought i could just get a hex key and put it on my cordless and goto town. i don't mind pulling the string but hell if you can make it easier then why not.

just buy the starter unless your a reverse engineer that can calculate the torque of your drill not to strip the starter let alone a fastner that small>>> in which case the brain damage will be worth more then $40
i can only assume its a propritarty size so one cant do as your thinking
Grind one till it fits
If you do please have someone video tape it and post a link to it here.the reason i ask is that i bought a troy bilt weed-eater and has the push to start option that i dont plan to buy as it is 40 bucks but it is a hex key on a electric motor so i thought i could just get a hex key and put it on my cordless and goto town. i don't mind pulling the string but hell if you can make it easier then why not.

So many years ago i dont even remember thisThis
I hope the guy figured it out now over 7 years later....

I sometimes start small engines when doing repairs and there not completely assembled with a cordless. What really helps is putting a ratchet adapter in between the power source and the hex or socket or whatever so when she starts running you don't get into trouble. I say keep at it & find a solution either a custom hex or find the right one.the reason i ask is that i bought a troy bilt weed-eater and has the push to start option that i dont plan to buy as it is 40 bucks but it is a hex key on a electric motor so i thought i could just get a hex key and put it on my cordless and goto town. i don't mind pulling the string but hell if you can make it easier then why not.
