Body: Steel, zinc plated, blue passivated finish
||GN 505 T-nuts can be inserted vertically into a T-slot similarly to the use of GN 508.1 rhombus nuts.
When the clamping bolt is tightened, 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 type MB, which is intentionally fitted with an overtight fit requiring a higher torque.
A 90° counterclockwise turn is sufficient to remove the bolt and T-nut, and to withdraw the two components from 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, establishing a good electrical contact.
