Rivetking 25C1IKFSYCE/P25 Rivet Nut 1/4-20 Steel 25 Pack

Product Description

The RIVETKING 25C1IKFSYCE/P25 is a closed end knurled rivet nut designed to provide a permanent, load-bearing threaded insert in thin-gauge base materials. Sized for a 1/4-20 thread and requiring a 25/64-inch drill hole, this countersunk-head fastener accepts a grip range of 0.027 to 0.165 inches, making it well suited for applications where panel thickness varies within that span. The knurled body resists rotation during installation and service. A zinc yellow dichromate finish provides corrosion resistance in light-duty environments. Installers in HVAC, electrical enclosure fabrication, and general sheet-metal work will find this nut appropriate for creating reliable threaded connections in blind-hole situations.

These rivet nuts are packaged in quantities of 25 per pack. They are used in residential and light commercial applications where threading directly into thin sheet metal, plastic panels, or composite materials is not practical. Common installation scenarios include HVAC equipment access panels, electrical enclosures, control boxes, and structural sheet-metal assemblies where a flush or near-flush countersunk head profile is required on the accessible face.

Key Features

• Closed end design keeps contaminants out of the threaded bore
• Knurled body resists spin-out during fastener torquing
• Countersunk head provides a low-profile flush finish on the work surface
• 1/4-20 thread size is a common standard in HVAC and light structural assemblies
• Zinc yellow dichromate finish offers corrosion resistance in indoor and light-exposure environments
• Grip range of 0.027 to 0.165 inches accommodates a variety of thin panel thicknesses

Compatibility

Designed as an OEM-style blind threaded insert for thin-gauge steel, aluminum, and composite panels requiring a 25/64-inch drill hole and a 1/4-20 threaded connection point.

Installation Notes

Installation requires a rivet nut setting tool matched to the 1/4-20 thread size. Verify the base material thickness falls within the 0.027 to 0.165-inch grip range before setting. Drill the hole to the correct 25/64-inch diameter and deburr the opening prior to inserting the nut to ensure a flush, secure set. De-energize or shut off any equipment panels before installing fasteners in live electrical or HVAC enclosures.
