6 Any Tools Needed? No Need! Just Turn the Handle! for Better Efficiency and Lower Costs Quick Manual Clamps with No Tools Imao One-Touch Clamps allow clamping and unclamping the workpiece just by turning the handle, without any tools. This one-touch feature helps to slash workpiece loading/unloading time, for drastic setup time reduction and increased productivity. Application Example

7 This extended line of One-Touch Clamps covers a wide range of clamping applications for small parts, and aluminum, zinc, cast-iron or steel parts.
