Micro™ Expanding Machinable Clamps

Jergens Micro™ Expanding Machinable Clamps are available with extra material on the clamping jaw so they can be machined to conform to the shape of your workpiece - enabling you to fixture unusual applications easily. The specially designed steel wedge spreads the clamping force uniformly on both sides of the aluminum channel. A unique locking plate is provided to make the clamp rigid while machining the jaw to your specifications, without vibration.

  • Material: Channel 7075-76 Aluminum
  • Compact design
  • Allows more parts to be mounted on a fixture
  • Mounting screws included
Note(s): 
  • Locking plate is used only to machine jaws. Remove to clamp the workpiece.
  • For the "A" dimension: The distance needed between workpieces for clamp clearance, drill, and tap mounting holes in the center of the “A” dimension.
  • The "F" dimension is the amount of machinable stock on jaws.
