GN 506 Roll-In T-Slot Nuts, Steel, for Aluminum Profiles, with Guide Step, M6, 5/16"

Gn 506 t-slot nuts can be rolled into position, they can be inserted at any point along the slot. The guide step positions the nut parallel and central within the slot, which makes it easier to move the nut and prevents from twisting during tightening. The spring loaded ball prevents an unwanted movement of the nut in the slot which is highly desirable on a bed with the t-slots in a vertical position.
