Gibraltar 41405TG T-slot Nut 3/8-16 Thread Steel

Product Description

The GIBRALTAR 41405TG is a tapped through T-slot nut machined from 1018 steel with a black oxide finish. It accepts a right-hand 3/8-16 thread and seats into T-slot tracks with a 0.5 inch slot width. The base measures 0.875 inches wide by 0.281 inches tall, and the overall length is 0.875 inches with an overall height of 0.5 inches. This style of T-slot nut is a standard fastening component used in fixturing, workholding, and machine table applications across manufacturing and fabrication environments. Installation requires no special tools beyond standard hand tools and a compatible T-slot track.

This nut is designed for use in T-slot tables and fixtures where a through-tapped connection is needed to secure clamps, stops, or other workholding components. It fits metric T-slot table sizes of 12.00 mm. Its compact base profile allows it to slide into position along the slot and then be engaged by a fastener from above. Machinists, toolmakers, and fabricators working with milling machines, welding tables, and similar slotted fixtures commonly use this type of nut.

Installation Notes

Slide the nut into the T-slot track before positioning your workholding component, as through-tapped T-slot nuts typically cannot be inserted once adjacent hardware is in place. Ensure the slot width of the table matches the 0.5 inch base clearance before installation. Standard hand tools are sufficient for assembly. Always confirm that the fastener thread pitch matches 3/8-16 before applying load.
