Gibraltar 41424TG T-slot Nut Through Tapped 7/8-9

Product Description

The GIBRALTAR 41424TG is a through-tapped T-slot nut machined from 1018 steel with a black oxide finish. It is designed to seat in standard T-slot table tracks and accept 7/8-9 right-hand threaded fasteners all the way through the nut body. The base measures 1-5/8 inches wide by 11/16 inches tall, giving it a stable bearing surface inside the slot. Overall length is 2 inches with an overall height of 1-1/8 inches. The part weighs 0.72 pounds and fits a 1-1/16 inch slot width, equivalent to 27.00 mm. Machinists, toolmakers, and fixture builders use this nut to anchor workholding components on milling machines, drill press tables, and other slotted platens.

This T-slot nut is suited for use on machine tool tables, welding fixtures, and modular workholding systems that use inch-standard T-slot tracks. The 7/8-9 through-tapped configuration allows a stud or bolt to pass completely through the nut, which is common in heavy workholding and clamping setups where full thread engagement and positive retention are required. The black oxide finish provides mild corrosion resistance in shop environments. Installation is handled by machinists and tool-and-die technicians during machine setup or fixture assembly.

Installation Notes

A licensed machinist or toolmaker should install this nut by sliding it into the T-slot track before securing the mating stud or bolt. Ensure the machine table or fixture is de-energized and the spindle is locked before adjusting workholding components. Use calibrated torque tools and follow the machine manufacturer's recommended clamping procedures. Do not overtighten, as doing so can damage the slot or distort the nut body.
