Specifications:
- Materials: The clamps are made from different materials such as SUS303 stainless steel, S45C steel, and polyamide with glass-fiber reinforcement.
- Dimensions: Detailed dimensions are provided for each model, including diameter (D1, D2, D3), length (L), and height (H).
- Strength: Shear and tensile strengths are specified for each model, with values ranging from 1800N to 3200N for shear strength and 1200N to 2600N for tensile strength.

Models and Variants:
- QCTH: Plastic knob
- QCTH-S: Metal knob
- QCTH-SUS: Stainless steel
- QCTHL-S: Low-height knob
- QCTHH: Hex socket head

Installation and Usage:
- Ensure the knob is at the "OFF" position before inserting the clamp.
- Turn the knob to the "ON" position to clamp, which will produce a clicking sound.
- For unclamping, reverse the steps.

Technical Information:
- Heat Resistance: The clamps can withstand temperatures up to 200°C.
- Proper Plate Thickness: Specific thicknesses are recommended for different models to ensure optimal clamping force.

Additional Features:
- The document includes information on cam receptacles and their installation, emphasizing machining accuracy and repeatability.
- Locating pins are recommended for higher accuracy in positioning.

Accessories:
- Supplied with socket-head cap screws made of stainless steel for secure installation.
