Rivetking /JF-4100/P25 Rubber Rivet Nut 8-32 25 Pack

Product Description

The RIVETKING /JF-4100/P25 is a rubber-insulated rivet nut designed for applications requiring vibration resistance, electrical isolation, or protection against abrasion at the fastener interface. The nut features a brass threaded insert encased in a rubber body, combining the grip strength of a standard blind nut with the insulating and cushioning properties of rubber. Thread size is 8-32 UNC. The flange measures 0.438 inches in diameter and 0.052 inches thick. Body diameter is 0.312 inches and overall length is 0.499 inches. This fastener is installed by licensed electricians, HVAC technicians, panel fabricators, and sheet metal workers wherever an insulated threaded anchor point is needed in thin-material assemblies.

This rivet nut is suited for residential and light commercial panel work, HVAC equipment enclosures, electrical cabinets, and sheet metal applications where direct metal-to-metal contact must be avoided. The rubber body accommodates material thicknesses ranging from a minimum grip of 0.015 inches up to a maximum grip of 0.156 inches, making it compatible with a range of thin-gauge substrates. Sold in a package quantity of 25 units, this SKU is appropriate for small jobs or service-van stock.

Installation Notes

Rivet nuts are installed using a rivet nut setting tool sized for the appropriate mandrel diameter; confirm the tool is rated for the body diameter before use. Ensure the substrate hole is clean and correctly sized to accept the 0.312-inch body without excessive clearance. Power down any electrical panel or enclosure before installing fasteners in live equipment. Follow applicable NEC guidelines when using insulated hardware in electrical enclosures.
