Tilt these clamps to hold workpieces at a variety of heights and angles. Also known as crocodile clamps, they have a grooved body and two clamping surfaces. Slide the clamping surfaces from groove to groove to change the angle of the clamp. They’re attached to the body, so you won’t lose them—these clamps are always ready to use. Pair them with T-slot nuts or bolts and a support to secure a workpiece, vise, or fixture to a machine table.
