Clamping screws - Ball type

Caution
- This product is used not to rotate face balls but to clamp workpieces.
(The face balls do not necessarily rotate depending on each caulking conditions of face balls.)
For Angle Type, a sphere of its hemisphere appears on the face, instead of a flat plane by its rotation.
In such a case, return its position using adhesive tape and magnet. Otherwise use Non-reverse Type to avoid rotations. - Please check the content on our website as the PDF does not contain the most up-to-date information.
