Gibraltar 61408G M12x1.75 Blind Tapped T-slot Nut

Product Description

The GIBRALTAR 61408G is a blind tapped T-slot nut designed for securing workpieces and fixtures to machine tables, jigs, and fixture plates that use standard T-slot tracks. Machined from 1018 steel with a black oxide finish, this nut provides corrosion resistance and a consistent seating surface in metric T-slot systems. The M12x1.75 right-hand thread accepts standard metric bolts and studs commonly used in machining and fabrication setups. At 32mm overall length and 19mm overall height, it offers solid material engagement without breakthrough on blind applications. Machinists, toolmakers, and fixture builders install this type of hardware during workholding setup and machine table configuration.

This nut is intended for metric T-slot table systems with a slot width of 17mm. It fits tables requiring a 17.46mm slot engagement width, with a base measuring 29mm wide by 11mm tall. The 32mm overall length provides adequate thread engagement for M12 fasteners. Typical applications include milling machine tables, drill press tables, welding fixture plates, and modular tooling systems that use metric T-slot profiles. It is sold individually and suited for both production environments and job-shop maintenance stock.

Key Features

• Blind tapped design prevents fastener breakthrough on shallow or finished table surfaces
• M12x1.75 right-hand thread for standard metric bolt and stud compatibility
• 1018 steel construction for reliable strength in workholding applications
• Black oxide finish provides mild corrosion resistance and reduced light glare
• Fits 17mm T-slot table tracks with 17.46mm slot engagement width
• Base dimensions of 29mm wide by 11mm tall seat securely within the slot channel

Compatibility

Designed for metric T-slot machine tables and fixture plates with a 17mm slot size. Verify slot width and bolt pattern against your specific table before installation.

Installation Notes

Installation is performed by machinists or toolmakers during workholding or fixture setup. Slide the nut into the T-slot track from the end or through an access opening, then align with the desired bolt position before threading in the fastener. Ensure the table surface is clear of chips and debris before seating the nut to prevent uneven clamping. Do not exceed the load rating of the fastener or the table manufacturer's torque recommendations for the slot size in use.
