I just completed ordering from Mister Worker some USAG 285x wrenches, purchased them individually rather than the 12pc.set, ( the individual wrenches are supposedly 28%off). I ordered: 10mm,11mm,12mm,13mm,14mm,15mm,16mm,17mm,18mm,19mm and 21mm (I passed on the 8mm and 9mm). I also ordered the tool roll for the 12pc 285x set for an additional $11. So...for 2 bucks more than the 12pc set; I loose the 8mm and 9mm, but gain the 21mm and a tool roll. $134 plus $19 shipping . (20mm is also available, but I passed on the 20mm). A lot more expensive than the $39 I paid for a 12pc set of the rebadged Craftsman v series shorter length wrenches, but the longer wrenches will be a nice addition. I really need to stop following GJ so much. UPDATE: thanks to the members Andres and Ryan for setting me straight. I assumed that the last 2 digits of the product number indicate the mm wrench size...not the case; for example 02850912 is a 10 mm, 02850914 is a 12mm and 02850916 is a 14mm! Hopefully my order cancelation request is honored, and I can try again!
