Marson M40349 Blind Rivet Button Head Aluminum 500 Pack

Product Description

The MARSON M40349 is an open end blind rivet with a button head profile, aluminum body, and steel mandrel. Blind rivets are used to join materials from one side when access to the back of the joint is limited or impossible. The button head provides a low-profile, rounded finish on the visible face of the fastener. The aluminum body keeps overall weight low while offering adequate shear and tensile strength for light to medium structural and sheet metal applications. The steel mandrel ensures reliable pull force during installation. This rivet ships in a package of 500 units, making it suitable for volume work on production lines or large field projects.

This rivet is suited for residential and light commercial applications where single-side fastening is required. Common install scenarios include sheet metal fabrication, HVAC ductwork assembly, electrical enclosures, trailer and vehicle panels, and general metal joining tasks. The 5/16 to 3/8 inch grip range accommodates a variety of material stack thicknesses, and the 3/16 inch nominal body diameter fits a standard hole size found across most sheet metal gauges used in trade work.

Key Features

• Open end blind rivet design allows installation from one side only - no rear access required
• Button head profile delivers a rounded, low-profile finished appearance on the set face
• Aluminum body reduces weight and resists corrosion in non-harsh environments
• Steel mandrel provides consistent break-load performance during installation
• 5/16 to 3/8 inch grip range accommodates varying material stack thicknesses
• Package of 500 supports high-volume fastening tasks without frequent reordering

Compatibility

Designed as an OEM-style fastener for use in standard blind rivet applications requiring a 3/16 inch body diameter and a 5/16 to 3/8 inch grip range across sheet metal, fabricated panels, and light structural assemblies.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, electricians, and general fabricators using a standard hand or pneumatic rivet tool sized for 3/16 inch body rivets. Drill or punch the hole to the correct diameter before setting the rivet. Ensure material stack thickness falls within the 5/16 to 3/8 inch grip range to achieve a proper mandrel break and full sleeve expansion. Worn or mismatched rivet tools can result in incomplete mandrel break - inspect the tool jaw set before use.
