Gibraltar 41407G Blind Tapped T-slot Nut 7/16-14

Product Description

The GIBRALTAR 41407G is a blind tapped T-slot nut designed for securing workpieces and fixtures to T-slotted machine tables, fixtures, and extrusion systems. Manufactured from 1018 steel with a black oxide finish, this nut features a 7/16-14 right-hand thread and is sized to fit a 0.5-inch slot width. The blind tap design closes off one end of the threaded bore, preventing chips and coolant from contaminating the threads during machining operations. Machinists, toolmakers, and fixture builders install this hardware when building modular clamping setups on mills, drill presses, and similar equipment.

This T-slot nut is suited for use in inch-measurement T-slot tables and fixture plates with a 13 mm nominal slot size. It fits standard machine table slots where a 7/8-inch base width is required. The compact base height of 9/32 inches and overall height of 1/2 inch allow installation in tight fixture arrangements. Typical applications include workholding setups on vertical milling machines and modular fixturing systems in production and job-shop environments.

Key Features

• Blind tapped bore keeps threads protected from chips and coolant contamination
• 7/16-14 right-hand thread for compatibility with standard inch-series clamping studs and bolts
• 1018 steel construction provides reliable strength for workholding loads
• Black oxide finish offers moderate corrosion resistance and reduces galling
• Fits 0.5-inch (13 mm) T-slot width for common machine table configurations

Compatibility

Designed for use in T-slotted machine tables, fixture plates, and extrusion systems with a 13 mm slot size and requiring a 7/16-14 inch-thread blind tapped nut.

Installation Notes

Slide the nut into the T-slot from an open end of the table or fixture plate before positioning the workpiece. Power down and de-energize any machine before making clamping adjustments on the table. Use appropriately rated clamping studs and step blocks per the machine tool manufacturer guidelines. Inspect thread condition before each use and replace any nut showing deformed or stripped threads.
