These miniature rocker clamps pivot completely away from the workpiece for easy loading and unloading. The clamp moves forward and downward into position and clamps straight down onto the workpiece for direct downward pressure. The cam handle is then pushed down for final workholding pressure. These clamps are ideal for repetitive accurate clamping operations. They come with a contact bolt that can be reversed for finished or rough workpiece surfaces. Mounts from the top with two mounting holes. The body and spindle made from 1045 alloy steel. The arm and joint made from 4135 alloy steel. Handle made from 4140 alloy steel.
