Gibraltar 41409TG T-slot Nut 1/2-13 Thread Steel

Product Description

The GIBRALTAR 41409TG is a tapped through T-slot nut machined from 1018 steel with a black oxide finish. It is designed to slide into standard T-slots on machine tables, fixtures, and workholding systems, providing a secure threaded anchor point for clamps, bolts, and tooling. The nut features a right-hand 1/2-13 thread and fits a 9/16-inch (0.5625 inch) slot width. Overall length is 1-1/8 inches and overall height is 5/8 inches. Machinists, toolmakers, and fixture builders use this hardware to build repeatable setups on milling machines, drill presses, and similar equipment.

This T-slot nut is suited for use on inch-measurement machine tables with a 15.00 mm (metric-equivalent) T-slot. It is commonly used in manufacturing, fabrication shops, and maintenance environments where workholding components must be repositioned frequently. The through-tapped design allows a bolt or stud to pass fully through the nut, accommodating a range of clamping stack heights without bottoming out.

Compatibility

Designed for use in standard T-slot machine tables and fixtures with a 9/16-inch slot width and a 15.00 mm T-slot size in the inch measurement system.

Installation Notes

Installation is performed by machinists or fixture builders during machine setup. Power down and de-energize any equipment before inserting or repositioning T-slot hardware on a machine table. Slide the nut into the T-slot from the open end and position it before threading in the clamping fastener. Do not overtighten the mating bolt, as this can deform the nut or damage the table slot.
