by the time you do all the screwing around , paying to get that thing fixed, you could purchase a brand new 3/8 and 1/2 torque wrenches and maybe a 1/4 for little stuff, all from harbor freight.
I cannot believe they sell that stuff that cheap. If your on the mailing list the have parking lot sales and other super extravaganza sale. I go to the one in Brockport NY every 3 months when I go to pickup all my purchases from ebay.
