Value Collection 45236 Knurled Rivet Nut 1/4-28 Unf Steel 50pk

Product Description

The VALUE COLLECTION 45236 is a knurled rivet nut insert designed for creating strong, threaded connections in thin-wall materials where back-side access is not available. Manufactured from steel with a cadmium-plated finish for corrosion resistance, this insert features a 1/4-28 UNF thread and a knurled body that resists rotation after installation. The 0.515-inch body length accommodates material grip ranges from 0.03 inches to 0.09 inches, making it well suited for sheet metal, tubing, and panel assemblies encountered in HVAC, electrical enclosure, and mechanical equipment fabrication work.

These inserts are used in applications where a permanent, load-bearing threaded anchor is needed in a drilled hole with no access to the reverse side of the workpiece. Common installation scenarios include HVAC unit panels, electrical junction boxes, structural brackets, and light-gauge steel assemblies. The 3/8-inch drill size and 0.4-inch body diameter are standard dimensions suited for typical sheet metal gauges found in residential and light commercial equipment. This package contains 50 inserts, making it appropriate for production runs or service stock.

Key Features

• 1/4-28 UNF thread standard for broad fastener compatibility in fine-thread applications
• Knurled body resists rotation during and after installation in drilled holes
• Cadmium-plated steel construction provides corrosion resistance in moderate environments
• Grip range of 0.03 inches to 0.09 inches accommodates light-gauge sheet metal and tubing
• Maximum installed length of 0.257 inches keeps the installed profile low on finished assemblies
• Package quantity of 50 supports production use and service inventory restocking

Compatibility

Designed as a standard rivet nut insert for use in any application requiring a 3/8-inch drilled hole and a 1/4-28 UNF threaded anchor point in thin-wall steel or similar materials.

Installation Notes

Installation is performed by machinists, HVAC fabricators, electricians, or general mechanical trades using a rivet nut setting tool matched to the 1/4-28 UNF thread. Drill the workpiece to 3/8-inch diameter before inserting. Ensure the workpiece thickness falls within the 0.03-inch to 0.09-inch grip range before setting. De-energize and isolate any electrical equipment or HVAC system panels before drilling or installing fasteners into live assemblies.
