Marson M40112 Open End Blind Rivet Size 44 Button 500pk

Product Description

The MARSON M40112 is an open end blind rivet in Size 44 with a button head profile, steel body, and steel mandrel. It is designed for one-sided fastening in applications where access to the back of the workpiece is limited or impossible. The rivet features a 1/4-inch head diameter, a grip range of 0.032 to 0.125 inches, and a body diameter of 0.129 to 0.125 inches. It is installed using a standard rivet tool and is suited for light- to medium-duty structural and sheet metal joining tasks across trade and commercial applications.

The M40112 is used in HVAC ductwork assembly, electrical enclosures, sheet metal fabrication, plumbing equipment panels, and general mechanical assembly work. The button head profile distributes clamping load across the material surface, making it appropriate for thinner gauge sheet metal and panel work. This rivet is sold in a package of 500 units, making it suitable for production work or technicians who install in volume.

Installation Notes

Blind rivets of this type are installed by sheet metal workers, HVAC technicians, electricians, and general mechanical trades using a compatible rivet puller or pneumatic rivet gun. Verify that the rivet tool mandrel jaw diameter matches the M40112 mandrel before use. Ensure material stack thickness falls within the 0.032 to 0.125-inch grip range to achieve full clamp and proper mandrel break. Dispose of spent mandrels safely after installation.
