Rivetking JK-SET Neoprene Well Nut Assortment 115 Piece

Product Description

The RIVETKING JK-SET is a 115-piece neoprene well nut assortment covering thread sizes from 8-32 up to 1/4-20. Well nuts are rubber-bodied fasteners with an embedded threaded insert that expand when torqued, creating a secure blind-side hold in panels, enclosures, and thin-wall materials. The neoprene construction provides flexibility and resistance to vibration loosening. This assortment includes three of the most common thread-and-body-diameter combinations, making it a practical bench stock for HVAC techs, electricians, and equipment installers who regularly fasten covers, access panels, and control boxes without rear access.

Well nuts in this size range are commonly used in light commercial and residential applications where a flush, vibration-resistant fastener is needed in sheet metal, plastic enclosures, or fiberglass panels. The assortment spans body diameters from 5/16 inches to 1/2 inches, fitting a range of hole sizes. Suitable for panel mounting, equipment access doors, electrical enclosures, and HVAC cabinet assembly. The three included size variants cover the most frequently encountered thread sizes in trade service work.

Installation Notes

Well nuts are installed by inserting the neoprene body into a pre-drilled or punched hole and tightening the mating screw until the body expands and clamps against the panel rear. Avoid overtightening, as excessive torque can tear the neoprene body. No special tools are required beyond a standard screwdriver or nut driver. Ensure the hole diameter matches the well nut body diameter before installation.
