Value Collection 45237 5/16-18 Unc Knurled Rivet Nut Insert 25pk

Product Description

The VALUE COLLECTION 45237 is a cadmium-plated steel knurled rivet nut insert designed for creating strong, threaded fastening points in thin-walled materials such as sheet metal, tubing, and panels. The knurled body resists rotation during installation, locking securely into the host material as the insert is set. This insert carries a 5/16-18 UNC thread standard and accommodates a grip range of 0.03 inches to 0.09 inches, making it well suited to light-gauge applications where a reliable internal thread is required. Licensed tradespeople and assembly technicians working in HVAC, electrical enclosure fabrication, and mechanical systems install these inserts as a standard fastening solution.

This insert is used in residential and commercial applications wherever a machine-screw thread must be anchored in material too thin for conventional tapping. Typical scenarios include sheet metal ductwork panels, electrical enclosure walls, equipment frames, and structural tubing. The 1/2-inch drill size requirement is a standard preparatory step before insert installation. Each package contains 25 inserts, sold in a minimum order quantity of one package.

Key Features

• 5/16-18 UNC internal thread for broad fastener compatibility
• Knurled body resists spin-out during and after installation
• Cadmium-plated steel construction for corrosion resistance
• Grip range of 0.03 inches to 0.09 inches suits light-gauge sheet material
• Body diameter of 0.528 inches with a body length of 0.615 inches
• Maximum installed length of 0.325 inches keeps the installed profile low

Compatibility

Designed as a standard 5/16-18 UNC knurled rivet nut insert for use in sheet metal and thin-walled panel applications requiring a 1/2-inch pilot hole.

Installation Notes

Installation is performed using a dedicated rivet nut setting tool sized for 5/16-18 inserts. The pilot hole must be drilled to 1/2 inch and deburred before the insert is placed. Disengage power and lock out any equipment before installing inserts in live electrical enclosures or mechanical assemblies, following applicable NEC or local code requirements. Do not over-set the insert, as excess pull force can deform the host material or strip the insert thread.
