Gibraltar 41432TG T-slot Nut 1-1/4-7 Thread Steel

Product Description

The GIBRALTAR 41432TG is a tapped through T-slot nut machined from 1018 steel with a black oxide finish. It accepts a 1-1/4-7 right-hand thread and fits a 36 mm (1.375 inch) T-slot, making it a standard choice for securing fixtures, workholding clamps, and tooling to machine tables and structural framing systems. The base measures 2.5 inches wide by 1.125 inches tall, and the overall length and height are 2.5 inches by 1.75 inches. The through-tapped design allows a bolt to pass completely through the nut, which simplifies alignment and stud-length adjustment during setup. Licensed machinists, millwrights, and fixture builders are the primary installers of this hardware.

This T-slot nut is sized for industrial machine tables, milling fixtures, modular workholding systems, and structural extrusion channels that accept a 36 mm T-slot profile. The 1-1/4-7 coarse thread is common in heavy-duty fixturing where clamping loads are high and vibration resistance is required. The black oxide finish provides moderate corrosion resistance in shop environments. Sold individually, this nut is suited for custom fixture builds, replacement of worn hardware, or low-quantity toolroom use.

Compatibility

Designed for machine tables, milling fixtures, and modular framing channels with a 36 mm T-slot. Confirm slot width and thread engagement depth before installation.

Installation Notes

Install and removal should be performed with the machine or workholding system fully de-energized and at rest. Slide the nut into the T-slot from an open end or by rotating it 90 degrees to drop it into the channel, then rotate to engage. Use a calibrated torque wrench appropriate to the stud or bolt size and follow the fixture or machine manufacturer torque guidance. Inspect thread condition and slot fit before applying clamping loads.
