Gibraltar 61406TG M12x1.75 Tapped Through T-slot Nut

Product Description

The GIBRALTAR 61406TG is a tapped through T-slot nut designed for securing workpieces and fixtures to T-slot tables and extrusions in machine tool, welding, and fabrication setups. Threaded M12 x 1.75 right-hand through the full body, this nut accepts standard M12 bolts and studs for positive clamping force. The base measures 22 mm wide by 9 mm tall, and the overall length is 29 mm with a 16 mm overall height. Manufactured from 1018 steel with a black oxide finish, it resists light corrosion while maintaining dimensional precision. Licensed machinists, toolmakers, and fabricators typically keep these on hand as standard hardware for fixture building.

This T-slot nut fits table slots sized for a 14 mm slot width and is rated for a 14.29 mm slot. It is suited for use on milling machine tables, drill press tables, surface plates, and aluminum extrusion framing systems that use metric T-slot profiles. The metric dimensioning makes it a natural fit for ISO-standard fixturing setups found in production machine shops, welding fixtures, and modular workholding systems. Single-piece packaging makes it easy to source in exact quantities for maintenance and repair applications.

Key Features

• M12 x 1.75 right-hand through thread for full bolt engagement
• Fits 14 mm nominal T-slot tables with a 14.29 mm slot width
• 1018 steel construction for strength and durability in fixturing applications
• Black oxide finish for light corrosion resistance
• Base dimensions of 22 mm wide by 9 mm tall for stable seating in standard T-slots
• 29 mm overall length provides adequate thread engagement depth

Compatibility

Designed for use in metric T-slot tables and extrusion systems requiring a 14 mm nominal slot width and M12 x 1.75 threaded fasteners.

Installation Notes

Installation is performed by machinists, toolmakers, or maintenance technicians without specialized certifications. Slide the nut into the T-slot before placing the workpiece or fixture, then align and thread the mating bolt or stud by hand before applying final torque with appropriate hand tools. Ensure the slot and nut surfaces are free of chips and debris before seating to maintain flush contact and prevent rocking. Do not exceed the torque capacity appropriate for M12 steel fasteners as determined by the fixture design requirements.
