Clamp nut aluminium.
Collet steel.

Clamp nut hard anodised.

The contour of the workpiece to be clamped is machined into the collet.

The collet must be pre-tensioned at a setting of 15° before the workpiece contour is machined in.

By using the engraved degree numbers, the same tightening torque can always be achieved for secure clamping of the workpiece, even without a torque wrench.

The radial clamping travel of the collet 03166-10-01910 is 0.025 mm per 15° rotation. The recommended clamping travel is 0.07 mm. The maximum permissible clamping travel is 0.38 mm.
The radial clamping travel of the collet 03166-10-04950 is 0.05 mm per 15° rotation. The recommended clamping travel is 0.1 mm. The maximum permissible clamping travel is 0.64 mm.

The positioning collar enables a precise seat.

Workpiece repeat accuracy: ± 0.02 mm.

The clamp nut is tightened using a hook wrench.
