Gibraltar 61403TG M8x1.25 Tapped Through T-slot Nut

Product Description

The GIBRALTAR 61403TG is a tapped through T-slot nut designed for use with T-slot fixture tables, workholding systems, and modular machine tooling setups. Threaded M8 x 1.25 with a right-hand thread direction, this nut slides into a T-slot track and accepts a standard M8 bolt or stud, allowing fixtures, stops, and clamps to be positioned and locked along the slot. Machined from 1018 steel with a black oxide finish, it provides corrosion resistance and hardness suited for repeated use in production environments. The base measures 16 mm wide by 6 mm tall, and overall length is 22 mm with an 11 mm overall height.

This T-slot nut is intended for use in T-slot table tracks with a 10 mm slot size. Typical applications include CNC machine tables, milling fixtures, welding positioners, and modular workholding systems where components must slide and lock into position quickly. It is commonly installed by machinists, toolmakers, and fixture builders working with metric T-slot tooling systems. Sold individually, making it practical for single-position replacements or small fixture builds.

Key Features

• Through-tapped M8 x 1.25 right-hand thread accepts standard metric fasteners
• Fits T-slot tracks with 10 mm slot opening
• 1018 steel construction for strength and durability in workholding applications

Compatibility

Designed for use in T-slot tables and fixtures with a 10 mm slot size, accepting M8 x 1.25 threaded fasteners in standard metric workholding configurations.

Installation Notes

Installation requires no special tools — slide the nut into the open end of the T-slot track or drop it into an access point, orient it to align with the slot channel, and engage the mating M8 fastener. Always ensure the machine table or fixture base is de-energized and stationary before adjusting workholding components. Verify slot dimensions match the 10 mm specification before ordering to ensure proper seating and clamping force.
