Tractor Supply for that 1 5/16 socket. Something like $6.95 when I bought one last year vs. $18.95 for a Craftsman that I use several times and then occupies major space in the Socet Drawer. My problem is the crap Impact Wrench that they sell with that Combo Kit. Be glad Crank Nut was it's baptism by fire. After a little use you'll be lucky to even get it to turn. Mine now laughs at Lug nuts torquesd to 50 lbs on Bugsy. Just goes hammer, hammer, hammer, laugh, laugh, at this fool. I can't decide new I.R. 650 lt lb. torque wrench or new drill dress to replace the one where the chuck becomesa flying projectile in the shop anytime I need to do some serious drilling. Cheap Indian Tool not even Chinese.
