J.W. Winco, Inc. announced it now offers series GN 506 T-Nuts with Guide Step in metric sizes.
These T-nuts can be turned into position, i.e., they can be inserted at any point along a slot. The spring-loaded ball prevents unwanted movement of the nut in the slot, which is highly desirable with the T-slots in a vertical position. For example, GN 506 T-nuts can be used to fit hinges to commercially available T-slot extrusion rails.
These RoHS compliant T-nuts are made from zinc plated, blue passivated C 45K steel. They are offered in threads from M3 to M8, to accommodate slot widths of 5 or 8 mm.
