Gibraltar 41423TG T-slot Nut 7/8-9 Thread Steel

Product Description

The GIBRALTAR 41423TG is a tapped through T-slot nut designed for securing workpieces and fixtures to T-slotted machine tables, vises, and fixture plates. It accepts a 7/8-9 right-hand thread and fits a 1-inch slot width, making it a standard choice for milling machine tables and modular fixturing systems. The nut is machined from 1018 steel and finished with black oxide for basic corrosion resistance. Its base measures 1-5/8 inches wide by 5/8 inches tall, with an overall length of 1-3/4 inches and an overall height of 1 inch. Machinists, toolmakers, and fixture builders install this nut when setting up work-holding on T-slotted surfaces.

This T-slot nut is suited for use in machine shops and industrial fabrication environments where T-slotted tables require reliable clamping hardware. Typical applications include milling machine setup, drill press table fixturing, and modular workholding configurations. The through-tapped design allows a stud or bolt to pass fully through the nut, providing flexibility in clamping height and setup depth. It is sized for 26 mm T-slot tables in metric references, while all dimensions follow the inch measurement system.

Compatibility

Designed for use in T-slots measuring 1 inch in width on standard milling machine tables, fixture plates, and T-slotted workholding systems sized for a 26 mm T-slot.

Installation Notes

Installation is performed by machinists or toolmakers during machine setup. Slide the nut into the T-slot from an open end before inserting and threading the clamping stud or bolt. Ensure the machine table is stationary and any power feed or spindle is off before adjusting workholding hardware. Do not overtighten the clamping assembly beyond the rated capacity of the stud and nut combination.
