Value Collection 138332003 Standard U Nut 1/4-20

Product Description

The VALUE COLLECTION 138332003 is a standard U nut designed for 1/4-20 threaded fasteners in sheet metal and panel assembly applications. Made from spring steel with a black phosphate and oil finish, this U nut clips onto panel edges and accepts a machine screw without requiring a pre-threaded hole in the workpiece. It accommodates panel material ranging from 0.025 inches to 0.15 inches thick, making it well suited for light-gauge metal panels, enclosures, and brackets. The overall length is 0.92 inches and the overall width is 0.56 inches. Electricians, HVAC technicians, and sheet metal fabricators regularly use U nuts when assembling control panels, equipment enclosures, and access covers.

This U nut is used in residential and commercial applications wherever a 1/4-20 screw must fasten to thin sheet metal without a tapped hole. Typical install scenarios include electrical enclosure assembly, HVAC cabinet fabrication, and equipment panel attachment. The spring steel construction provides consistent clamping force and retains the nut on the panel edge during assembly, keeping both hands free for screw installation. The center-to-edge dimension is 35/64 inches, which determines the screw centerline position relative to the panel edge.

Key Features

• 1/4-20 thread size for use with standard 1/4-20 machine screws
• Accepts panel thickness from 0.025 inches to 0.15 inches
• Spring steel construction provides firm clip retention on panel edges
• Black phosphate and oil finish for corrosion resistance in typical indoor environments
• Center-to-edge dimension of 35/64 inches for consistent screw positioning
• Standard U nut profile fits common panel edge profiles in enclosure and cabinet work

Compatibility

Designed as an OEM-style replacement or general-use U nut for light-gauge sheet metal panels and enclosures requiring a 1/4-20 threaded fastening point in the 0.025 inches to 0.15 inches material thickness range.

Installation Notes

Installation requires no special tools — the U nut slides or clips onto the panel edge by hand before the screw is driven. Power down and de-energize any electrical enclosure before performing panel fastener work. Verify panel thickness falls within the 0.025 inches to 0.15 inches specified range before installation, as over- or under-thickness panels will reduce clamping force and thread engagement. Follow applicable NEC or equipment manufacturer guidelines when working inside electrical enclosures.
