Gibraltar 61408TG M12x1.75 Tapped Through T-slot Nut

Product Description

The GIBRALTAR 61408TG is a tapped through T-slot nut designed for use with metric T-slot tables and fixturing systems. Machined from 1018 steel with a black oxide finish, this nut accepts an M12x1.75 right-hand thread and seats into a 17mm table slot. The base measures 29mm wide by 11mm tall, with an overall length of 32mm and an overall height of 19mm. It is used in machine tool setups, workholding fixtures, and precision clamping applications where a secure, reusable threaded anchor is required. Installation is performed by machinists, toolroom technicians, and fixture builders.

This T-slot nut is suited for metric T-slot tables common in milling machines, drill presses, surface plates, and modular fixturing systems. The through-tapped design allows a stud or bolt to pass fully through the nut, enabling flexible clamping arrangements. The black oxide finish provides mild corrosion resistance for shop-floor environments. It fits table slots with a nominal slot width of 17mm and is sold individually.

Installation Notes

T-slot nuts are installed by sliding them into the open end of a T-slot or dropping them into the slot at a relief point, then rotating 90 degrees to engage the slot walls. Ensure the machine table or fixture is de-energized and stationary before installing or repositioning nuts. Verify thread engagement depth is sufficient for the applied clamping load before securing. Use appropriate torque practices for M12 fasteners per fixture design requirements.
