These clamps are made completely of tempered forged steel. They are excellent for welding and woodworking alike. They have a clamping pressure of up to 660 pounds!
The mightymini's sliding arm moves to position itself right next to your work-piece to support the acme threaded screw! By comparison, when a C-clamp is used to do the job of a 1" C-clamp, the point of support for the screw does NOT move... leaving the extended screw to do all of the work. The results can be a clamp that walks... or worse, a screw that bends or breaks.
FEATURES:
RAIL, FIXED JAWS AND PRESSURE PLATE HEAT-FORMED IN ONE PIECE FROM COLD DRAWN PROFILED STEEL....optimized for high static stress loadings, tempered and electro galvanized.
