Au-ve-co Products 13223 Standard U Nut M4.2x1.41

Product Description

The AU-VE-CO PRODUCTS 13223 is a metric standard U nut designed for M4.2x1.41 screws, intended for use with panel stock ranging from 3 to 4mm thick. The part is manufactured from spring steel and features a yellow finish. U nuts of this type clip onto sheet metal edges or flanges and provide a captured, vibration-resistant threaded fastening point without requiring access to the back side of the panel. This hardware is widely used in HVAC cabinet assembly, electrical enclosure fabrication, and light-gauge metal panel applications where reliable, repositionable thread attachment is required.

This U nut fits panels between 3 and 4mm thick and accepts an M4.2x1.41 screw thread. The 7mm center-to-edge dimension positions the fastener correctly on standard-gauge sheet metal flanges. These fasteners are commonly installed during original equipment manufacturing and in field service when replacing or retrofitting HVAC cabinet panels, electrical enclosures, and similar light-gauge metal assemblies. They are sold with a minimum order quantity of 50 pieces per unit of measure.

Key Features

• Accepts M4.2x1.41 metric screw thread
• Compatible with panel stock 3 to 4mm thick
• Spring steel construction provides inherent clip retention and thread tension
• 7mm center-to-edge dimension for consistent flange positioning
• Yellow finish for corrosion resistance and visual identification
• Standard U nut profile clips onto panel edges without rear access

Compatibility

Designed as an OEM-style replacement or service fastener for light-gauge sheet metal panels and flanges accepting M4.2x1.41 metric screws with a panel thickness between 3 and 4mm.

Installation Notes

U nuts are typically installed by HVAC technicians, electricians, and sheet metal mechanics during panel assembly or service. Clip the U nut onto a clean, burr-free panel flange before threading the fastener. Ensure the panel thickness falls within the 3 to 4mm specification to maintain proper spring tension and thread engagement. Power down any associated electrical or mechanical system before removing or replacing cabinet panels.
