Welding Clamps - Intergrip Panel Clamps Set of 4
Product Review (submitted on August 24, 2012):
like the others said, a little weld on the post. One thing, the tack welds on the screw are very minimal. i can see them not holding up with much use. just if you have the welder out anyway, just give it another zap. otherwise i have to say very nice to have. bought 2 sets on sale. NOT worth full price because of quality but nice addition to the tool box when 1/2 price :) and that ONE time you really need them, it will be worth it.
