T-nuts GN 505 can be inserted vertically into a T-slot like rhombus T-nuts GN 508.1.

When tightening the clamping bolt, the nut will be forced into a crosswise position by the applied torque and firmly anchored in the T-slot.

This action is achieved by using T-nut with increased torque (Type MB) which is intentionally fitted with an overtight fit requiring a higher torque.

To remove the bolt and T-nut a 90° anticlockwise turn is sufficient to withdraw the two components with the clamped workpiece.

The clamping face of the T-nut is serrated to ensure that a possible plating coat in the T-slot is penetrated to establish a good electrical contact.
