Au-ve-co Products 20834 Open End Blind Rivet Large Flange

Product Description

The AU-VE-CO PRODUCTS 20834 is an open end blind rivet with a large flange head, aluminum body, and steel mandrel. It is designed for one-sided fastening applications where access to the back of the workpiece is not possible. The large flange head spreads clamping force over a wider surface area, reducing pull-through on softer or thinner materials. With a head diameter of 0.551 inches, a body length under head of 0.433 inches, and a maximum grip of 0.25 inches, this rivet suits light-duty assembly work across HVAC, sheet metal, plumbing, and general trade applications. Installation requires a standard blind rivet tool.

This rivet is suited for residential and commercial trade installations where single-side fastening is required. Typical applications include joining sheet metal panels, HVAC ductwork, electrical enclosures, and similar thin-material assemblies. The aluminum body resists corrosion in moderate environments, and the steel mandrel provides reliable pull strength during setting. The silver finish blends with bare aluminum and galvanized sheet materials. This rivet is sold individually with a minimum order quantity of 15 units.

Key Features

• Large flange head distributes clamping load to reduce pull-through on thin or soft substrates
• Aluminum body offers lightweight corrosion resistance for sheet metal and ductwork applications
• Steel mandrel delivers consistent setting strength and reliable break performance
• Maximum grip of 0.25 inches accommodates common thin-material stack-ups
• Maximum hole diameter of 0.236 inches fits standard rivet hole sizes for 1/4-inch body rivets
• Open end design allows for standard blind installation with a hand or pneumatic rivet tool

Compatibility

Designed as an OEM-style replacement and general-use blind rivet for light-duty sheet metal, HVAC ductwork, electrical enclosure, and thin-panel fastening applications requiring a large flange head profile.

Installation Notes

Installation is performed by a sheet metal mechanic, HVAC technician, or electrician using a standard hand-operated or pneumatic blind rivet tool sized for the appropriate mandrel diameter. Drill or punch the workpiece to the correct hole diameter before setting. Verify material stack-up does not exceed the maximum grip range before selecting this rivet. Do not reuse a rivet once the mandrel has been pulled and broken.
