Marson M40215 Open End Blind Rivet Aluminum 500 Pack

Product Description

The MARSON M40215 is an open end blind rivet with a button head profile, aluminum body, and aluminum mandrel. Designed for one-sided fastening where access to the back of the work material is not possible, it sets flush-free dome-style heads without requiring a backing surface. The body diameter ranges from 0.129 to 0.125 inches and the grip range runs from 0.126 to 0.187 inches, making it suitable for thin to medium material stacks. The 1/4-inch head diameter provides a broad bearing surface. Sold in a 500-piece package, this rivet is a standard shop-stock item for fabricators, sheet metal workers, HVAC installers, and general tradespeople.

This rivet is used across residential and light commercial applications wherever aluminum-to-aluminum or aluminum-to-compatible-substrate fastening is required. Common install scenarios include sheet metal ductwork assembly, HVAC panel fabrication, electrical enclosure work, and light structural sheet assemblies. The open end design allows the mandrel to pass through after setting, which is standard for general-purpose blind rivet work. The button head style distributes clamping load over a wider area than countersunk alternatives, making it a practical choice for soft or thin sheet materials.

Installation Notes

Installation requires a standard blind rivet pulling tool sized for the body diameter of this fastener. Ensure the rivet hole diameter matches the body diameter specified before setting. Do not exceed the stated grip range, as oversized or undersized material stacks will result in improper set and reduced holding strength. Inspect the set head and mandrel break point after installation to confirm full engagement.
