Au-ve-co Products 23939 Structural Blind Rivet Dome Head

Product Description

The AU-VE-CO PRODUCTS 23939 is a structural blind rivet designed for high-load fastening applications where access to only one side of the workpiece is available. It features a dome head profile, an aluminum body, and an aluminum mandrel, with a black finish. The rivet accommodates a grip range of 0.08 to 0.375 inches and requires a 0.25-inch hole diameter. At 13.50 mm under-head length, it is suited for sheet-to-sheet and sheet-to-structural member joints in HVAC, sheet metal, and light structural assembly work. Installation requires a standard blind rivet tool matched to the 0.25-inch shank.

This rivet is used in applications where structural pull-out and shear strength exceed the performance envelope of standard open-end blind rivets. Typical scenarios include ductwork assembly, equipment enclosure fabrication, metal panel attachment, and HVAC unit casing repairs. The dome head distributes clamping load over a wider surface area, making it appropriate for softer substrates and thin-gauge sheet metal. Both the body and mandrel are aluminum, keeping the fastener lightweight and corrosion-resistant in typical interior and light exterior service environments.

Key Features

• Structural rivet type - higher pull-out and shear strength than standard blind rivets
• Dome head profile distributes clamp load across a broader bearing surface
• Aluminum body and aluminum mandrel for lightweight, corrosion-resistant performance
• Grip range of 0.08 to 0.375 inches accommodates varying material stack thicknesses
• Designed for 0.25-inch hole diameter - consistent with standard rivet tooling
• Black finish for a clean appearance on visible panel and casing installations

Compatibility

Designed as an OEM-style structural blind rivet for use in sheet metal, HVAC casing, ductwork, and light structural fabrication applications requiring a 0.25-inch hole diameter and a grip range up to 0.375 inches.

Installation Notes

Install using a blind rivet tool sized for a 0.25-inch mandrel. Ensure the mating hole is clean, properly sized, and free of burrs before insertion. Do not overdrive or re-use a set rivet. For structural assemblies, verify joint design load requirements against the rivet manufacturer specification sheet before specifying quantity and pattern.
