I know its alittle late but tool truck small allens are no good when compaired to RC specific allen drivers. No you can not special order true hardened allens off tool trucks in any form T,L,or socket.The ones actually made by the tool truck companys & not just rebadged KD or Lyle are forged & while forged steel tools are hard they are no where near as hard as the drill bit blanks many RC specific tools are made from.
You can still cut glass with the decade old MIP drivers I have or the Bullit ones that are 4-5 years old.You cant do that with brand new Snapon tools.
Please dont take this as picking on tool truck tools,I have well over $150,000. in snapon & matco tools & boxes that I use every day to feed my family for the last 15 years.
For 1.5,2.0,2.5,3.0mm hex drivers tool trucks are a frustrating waste of money.
