I've found that Tox joints are no where near as strong as Tog-L-Loc joints. Also Tox's tooling is more expensive. I would go with Tog-L-Loc if you are joining sheet metal.
More information about Tog-L-Loc can be found at www.btmcorp.com or www.tog-l-loc.com
BTM offers a wide variety of presses featuring the Tog-L-Loc system. They also offer grippers, clamps, air/oil cylinders and locators. Their website is located at www.btmcorp.com.
