FAQs about Snap-In Clamps

Clamping force refers to the force generated when four balls grip the clamping pin, pulling the plate inward.

If a tensile load exceeding the clamping force is applied, a gap may occur. However, the holding force refers to the ability to maintain the gap between the plates within 0.1 mm.

Tensile strength refers to the maximum load that the clamp can withstand when the plate is pulled away from the base.

Even when a tensile load exceeding the clamping force is applied, a gap may occur between the plates, but the wedge structure minimizes the gap.

Please refer to the technical data of each product below for details.

Part Number Clamping Force (N) Holding Force (N) Tensile Strength at Failure (N)

Yes.
This product can be used in applications subject to offset (moment) loads.
Please refer to the PDF below for guidelines on load calculations, gap generation, and precautions regarding product failure before determining suitability.

Guidelines for Applications with Offset (Moment) Loads

No.
The Mechanical Strength values do not include a safety factor.
These values represent the load levels at which failure can occur and should not be considered allowable loads.

To clamp, simply insert the clamp onto the pin without pressing the button.
To unclamp, press the button while removing the clamp.

Please refer to the table below for the typical button pressing force.

Durability testing is conducted under no-load conditions, focusing on repeated clamping and unclamping of the clamper.
The results of the durability tests are shown below for reference when evaluating product suitability.

Yes, provided that the combined thickness of the workpiece and the mounting plate is within the T dimension shown in the figure (tolerance: ±0.2 mm).

However, inserting a workpiece reduces the thickness of the mounting plate. Therefore, it is recommended to ensure sufficient plate thickness for proper operation.

Yes, the product can be used with a single clamp and clamping pin set.
However, we recommend using locating pins to prevent the plate from rotating.
