Marson M40252 Open End Blind Rivet Button Head Aluminum 500pk

Product Description

The MARSON M40252 is an open end blind rivet with a button head profile, aluminum body, and aluminum mandrel, sold in a package of 500. Blind rivets are installed from one side of a workpiece without access to the back, making them a standard fastener in sheet metal fabrication, HVAC ductwork, enclosures, and structural panel assembly. The M40252 features a 3/8-inch head diameter, a body diameter of 0.192 to 3/16 inches, and a grip range of 0.376 to 1/2 inches. The aluminum-on-aluminum construction keeps weight low and resists corrosion in most indoor and light outdoor environments. A licensed sheet metal mechanic or fabricator installs this rivet using a standard hand or pneumatic rivet tool.

This rivet is suited for light-duty to medium-duty fastening applications where access to only one side of the material is available. Common uses include HVAC duct assembly, electrical enclosure fabrication, metal roofing and flashing, trailer panels, and general sheet metal work. The button head profile sits low and provides a clean, rounded finished face on the visible side of the joint. The 500-piece package quantity supports production or shop use where consistent replenishment is required.

Installation Notes

Install using a hand rivet tool or pneumatic rivet gun fitted with the appropriate nosepiece for a 3/16-inch body diameter. Drill or punch the pilot hole to the correct diameter for a clean, snug fit before inserting the rivet. De-energize or de-pressurize any assembly before fastening rivets to live panels or enclosures. The mandrel stem will eject during setting - use eye protection and ensure the work area is clear.
