Gibraltar 41420TG T-slot Nut 3/4-10 Thread Steel

Product Description

The GIBRALTAR 41420TG is a tapped through T-slot nut designed for securing workpieces and fixtures to T-slotted tables, extrusions, and machine tool beds. It features a 3/4-10 right-hand thread tapped completely through the body, allowing full bolt engagement from either face. The nut is machined from 1018 steel and finished with a black oxide coating for corrosion resistance. The base measures 1.625 inches wide by 0.625 inches tall, and the overall dimensions are 1.75 inches long by 1 inch tall. Machinists, fabricators, and tooling technicians install this hardware when building jigs, fixtures, or workholding setups on slotted table surfaces.

This T-slot nut is intended for use in 1-inch wide T-slots, equivalent to a 26 mm slot, commonly found on milling machine tables, welding tables, modular fixturing plates, and industrial workbenches. It is suited to both light production and heavy-duty fixturing environments where a through-tapped nut is preferred over a flanged or stud-style alternative. The right-hand thread orientation is standard for use with conventional cap screws and hex bolts.

Key Features

• Through-tapped 3/4-10 right-hand thread for full bolt engagement from either side
• Fits 1-inch (26 mm) T-slots on machine tables and fixturing systems
• 1018 steel construction for reliable strength in workholding applications
• Black oxide finish provides mild corrosion resistance and reduces light glare
• Base dimensions of 1.625 x 0.625 inches seat securely in standard T-slot channels
• Overall length of 1.75 inches and height of 1 inch for positive thread engagement depth

Compatibility

Designed for use in T-slots measuring 1 inch wide (26 mm), as found on standard milling machine tables, modular fixturing plates, and slotted workholding surfaces that accept 3/4-10 threaded fasteners.

Installation Notes

Installation is performed by machinists or tooling technicians without the need for special tooling beyond the mating fastener. The nut is inserted into the T-slot channel and oriented so the base flanges engage the slot rails before threading in the clamping bolt. Ensure the slot width matches the nut base dimensions before assembly to prevent binding or improper seating. De-burr the slot channel if necessary to allow smooth nut travel.
