The MARSON M40221 is an open end blind rivet with a button head profile, aluminum body, and aluminum mandrel. It is designed for one-sided fastening applications where access to the back of the workpiece is limited or impossible. The button head provides a low-profile, finished appearance on the surface. With a body diameter of 0.129 to 0.125 inches and a grip range of 0.313 to 0.375 inches, this rivet accommodates a range of material stack thicknesses. Head diameter measures 0.25 inches. This fastener is sold in a package quantity of 500 and is suited for production and field use by sheet metal workers, HVAC installers, and general trade professionals.

This rivet is commonly used in residential and light commercial construction, HVAC ductwork fabrication, sheet metal assemblies, and general manufacturing applications. Its all-aluminum construction makes it appropriate for use in environments where galvanic compatibility with aluminum substrates is a priority. The 500-count package supports both high-volume production runs and recurring service work where consistent fastener availability is required.
