Te-co 41609 Flange Nut 1-8 Unc 2 in Black Oxide Steel

Product Description

The TE-CO 41609 is a heavy-duty flange nut machined from 12L14 steel with a black oxide finish. Designed for UNC 1-8 threaded fastener applications, it features a 2-inch flange diameter that distributes clamping load across a wider bearing surface, reducing the risk of surface damage or fastener pull-through. The nut stands 1.25 inches tall with a 0.25-inch flange height and measures 1.625 inches across the flats. Weighing 0.625 pounds, it is suited for industrial fixturing, workholding, and mechanical assembly work where a reliable, corrosion-resistant fastening solution is required. The black oxide treatment provides moderate corrosion resistance and reduces light reflection in shop environments.

This flange nut is used in industrial and manufacturing settings, particularly in workholding and fixturing applications. It is appropriate for machine tables, jig plates, and clamping setups where load distribution across the flange face is critical. Trades and technicians working with T-slot tables, press fixtures, or structural mechanical assemblies will find this nut suited to high-load UNC threaded configurations. It conforms to TCMAI fastener standards and is measured in the inch system, making it compatible with standard inch-series tooling and hardware.

Key Features

• 12L14 steel construction for consistent machinability and strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• 2-inch flange diameter spreads clamping load to protect mating surfaces
• UNC 1-8 thread standard for broad inch-series fastener compatibility
• Meets TCMAI fastener standards
• Compact 1.25-inch nut height suits space-constrained fixturing setups

Compatibility

Designed as an OEM-style replacement or direct-use flange nut for industrial workholding and fixturing applications using UNC 1-8 inch-series threaded hardware.

Installation Notes

Installation is performed by qualified machinists or mechanical technicians familiar with inch-series UNC fastener systems. Ensure mating threads are clean and free of debris before installation. Use an appropriately sized wrench sized to the 1.625-inch across-flats dimension. De-energize or lock out any powered equipment before servicing fasteners in live assemblies, in accordance with applicable OSHA lockout/tagout procedures.
