Frequently Asked Questions
What do the "Star Outside" and "Square Inside" measurements represent?
"Star Outside" indicates the external diameter of the star-shaped profile, while "Square Inside" refers to the internal width of the square drive connection. Both are measured in millimeters (mm).
How do I choose the correct height for my application?
The height ranges from 12mm to 38mm. You should select the height based on the clearance available in your working space and the depth of the connection shaft you are targeting.
