Product description


GN 505 serrated quarter-turn T-slot nuts can be inserted vertically into a T-slot similarly to the use of GN 508.1 rhombus T-slot nuts.

When tightening the mounting screw, the nut will be forced into a crosswise position by the torque and thus anchored in the T-slot.

This process is supported by the version with increased friction torque (type MB). In this case the nut thread is deliberately stiff.

A 90° turn of the screw / nut is sufficient to remove the two components.

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