Gibraltar 41410G Blind Tapped T-slot Nut 1/2-13

Product Description

The GIBRALTAR 41410G is a blind tapped T-slot nut designed for securing workpieces and fixtures to T-slot tables, rails, and extrusions. The blind tap design closes off the bottom of the threaded bore, preventing chip and coolant intrusion in machine tool environments. Threaded at 1/2-13 UNC with a right-hand thread direction, it accepts standard 1/2-13 bolts and studs. The nut is machined from 1018 steel and finished with a black oxide coating for mild corrosion resistance. It fits a 5/8-inch slot width and is sized for 16 mm T-slot table systems. Machinists, tool and die technicians, and fixture builders install this hardware on milling machines, drill presses, and modular workholding tables.

This nut is suited for use on machine tool tables and modular fixturing systems that use inch-dimensioned T-slots. The 1-1/8-inch overall length and 1-inch base width provide a stable seating footprint in the slot channel. The 5/8-inch overall height keeps the nut profile low within the slot. Typical applications include clamping fixtures, vise mounting, stop blocks, and strap clamp setups on manual mills and machining centers. Each unit is sold individually at a package quantity of one.

Compatibility

Designed for use in T-slot tables and fixturing systems with a 5/8-inch slot width or equivalent 16 mm slot size, using 1/2-13 UNC fasteners.

Installation Notes

Installation is performed by machinists or fixture technicians. Always de-energize and lock out the machine before installing or adjusting T-slot hardware on a machine tool table. Slide the nut into the T-slot from an open end or drop it in through the slot opening and rotate 90 degrees to seat the base flanges in the channel. Confirm the nut is fully seated in the slot before applying clamping load to avoid rocking or pull-out under load.
