Marson M42285 Open End Blind Rivet Aluminum 100 Pack

Product Description

The MARSON M42285 is an open end blind rivet with a button head profile, aluminum body, and aluminum mandrel. Blind rivets are installed from one side of the workpiece, making them the standard fastener choice when access to the back of the joint is limited or impossible. The M42285 features a 0.5-inch head diameter, a grip range of 0.376 to 0.5 inches, and a body diameter of 0.257 to 0.25 inches. This rivet is installed using a standard rivet tool and is suited for light- to medium-duty sheet metal, panel, and bracket assembly work across HVAC, electrical enclosure, and general trade applications.

The M42285 is used wherever a clean, flush-profile fastener is needed on aluminum or compatible sheet materials. The button head style provides a low-profile, rounded face on the visible side of the joint. Typical applications include duct fabrication, equipment enclosure assembly, signage mounting, and light structural panel work. Each package contains 100 rivets, making it a practical unit for job-site and shop use alike.

Installation Notes

Blind rivets of this type are installed by a sheet metal mechanic, HVAC technician, or general trade professional using a rivet gun matched to the body diameter. Ensure the drilled hole diameter matches the rivet body spec before installation to achieve full clamp force. Insert the rivet mandrel into the tool nose, seat the rivet head flush against the workpiece, and pull the tool trigger until the mandrel snaps. Inspect the set head on the blind side where accessible to confirm full flare and seating.
