Fixture clamps have a low-profile clamp block that presses onto the end of a workpiece to secure it to a worktable. They exert high clamping force while leaving most of the workpiece exposed for machining. A threaded stud fastens the clamp to a threaded fixture slot in a worktable. Cam action fixture clamps have a low profile to secure parts from the side while leaving the entire top of the part free for machining. Edge and toe clamps apply pressure to the side of a workpiece and are often used with positioning clamps. Wedge clamps have a small footprint and apply clamping force simultaneously on both sides of the clamp to secure parts in repeated production applications. Inside-diameter fixture clamps are self-centering and hold parts from inside a bore or cavity to provide full access to the outside of the part.
