Au-ve-co Products 23861 Open End Blind Rivet Large Flange

Product Description

The AU-VE-CO PRODUCTS 23861 is an open end blind rivet designed for single-side fastening applications across sheet metal, HVAC enclosures, electrical panels, and light structural assemblies. It features a large flange head with a 3/8 inch head diameter, which distributes clamping load over a wider surface area to reduce pull-through in softer or thinner materials. The body is aluminum and the mandrel is stainless steel, providing corrosion resistance at the mandrel break point. Overall length under the head is 0.563 inches, with a grip range of 1/32 inch minimum to 11/64 inch maximum and a maximum hole diameter of 1/8 inch. The rivet ships in a black finish.

This rivet is suited for residential and light commercial applications where a blind fastener is required and access is limited to one side of the material. Common uses include HVAC duct assembly, equipment panels, electrical enclosures, and sheet metal fabrication. The large flange head makes it a preferred choice when the base material is a softer substrate or when pull-through resistance is a priority. The stainless steel mandrel adds durability in mildly corrosive or outdoor-adjacent environments.

Key Features

• Large flange head at 3/8 inch diameter for improved pull-through resistance
• Aluminum body keeps installed weight low and resists general corrosion
• Stainless steel mandrel provides added corrosion resistance at the break point
• Grip range of 1/32 inch to 11/64 inch accommodates thin material stacks
• Designed for 1/8 inch maximum hole diameter for a snug fit in standard drilled or punched holes
• Black finish for a clean appearance in visible or finished panel installations

Compatibility

Designed as an OEM-style blind rivet for use in sheet metal, HVAC, electrical, and light fabrication applications requiring a 1/8 inch hole and grip range of 1/32 inch to 11/64 inch.

Installation Notes

Install with a standard hand or pneumatic rivet tool sized for 1/8 inch body diameter rivets. Drill or punch the mating hole to no larger than 1/8 inch for proper mandrel pull and flange seating. Ensure both layers of material fall within the 1/32 inch to 11/64 inch grip range before setting the rivet, as under- or over-grip will compromise joint strength. Wear eye protection during installation, as mandrel stems eject under tension.
