Gibraltar 61401TG M6x1.00 Tapped Through T-slot Nut

Product Description

The GIBRALTAR 61401TG is a tapped through T-slot nut machined from 1018 steel with a black oxide finish. It is designed to seat in standard T-slot tracks on milling machine tables, fixture plates, workholding systems, and similar machine tool setups. The M6x1.00 right-hand thread runs through the full body, allowing a fastener to engage from either face. The nut fits an 8 mm table slot and has a base measuring 14 mm wide by 6 mm tall, with an overall length of 19 mm and an overall height of 10 mm. Machinists, toolmakers, and fixture builders install this nut when setting up workholding, stops, clamps, or jigs on T-slotted surfaces.

This nut suits metric T-slot applications in both manual and CNC machining environments. The through-tapped design gives full thread engagement across the body, supporting consistent clamping force without the risk of bottoming out a fastener. The black oxide coating provides a degree of corrosion resistance appropriate for shop floor conditions. It is sold individually, making it practical for single-position replacement or low-quantity fixture builds alongside matched T-slot bolts and strap clamps.

Compatibility

Designed for use in T-slot tracks with an 8 mm slot width, consistent with standard metric milling machine tables and fixture plate systems that accept M6 fasteners.

Installation Notes

Installation is performed by machinists or toolmakers as part of workholding or fixture setup. Always power down and lock out the machine before inserting or adjusting T-slot hardware. Slide the nut into the open end of the T-slot track and rotate 90 degrees to seat the base, then thread in the mating bolt or stud by hand before applying final torque with a wrench. Confirm the nut is fully seated in the slot before applying clamping loads to prevent pull-out or slot damage.
