Marson M40149 Open End Blind Rivet Button Head Steel 500pk

Product Description

The MARSON M40149 is an open end blind rivet with a button head profile, steel body, and steel mandrel, designed for one-sided fastening in sheet metal, structural panels, and fabricated assemblies. The body diameter ranges from 0.192 to 3/16 inches, with a grip range of 0.313 to 3/8 inches and a head diameter of 3/8 inches. This rivet is suited for applications where access to the back side of the workpiece is not possible, making it a reliable fastener choice for HVAC cabinet work, electrical enclosures, sheet metal fabrication, and general trade installations. Each package contains 500 rivets.

This blind rivet fits common one-sided fastening scenarios encountered in light structural, mechanical, and electrical enclosure work. The button head style sits low and distributes clamping load across a wider surface area, reducing pull-through risk in thinner substrates. The all-steel construction handles the mechanical demands of HVAC equipment panels, control boxes, ductwork flanges, and similar commercial and residential trade applications. Licensed HVAC technicians, sheet metal workers, and electricians routinely use this fastener type during equipment installation and panel fabrication.

Key Features

• Open end design allows post-set deformation for secure clamping on blind-side applications
• Button head profile provides broad load distribution and a low-profile finished appearance
• Steel body and steel mandrel deliver strength suitable for structural sheet metal work
• Grip range of 0.313 to 3/8 inches accommodates variable material stack thicknesses
• Body diameter of 0.192 to 3/16 inches fits standard rivet hole sizing

Compatibility

Designed as an OEM-style open end blind rivet for use in standard rivet tools accepting 3/16 inch body diameter fasteners, suitable for single-sided fastening in sheet metal and light structural assemblies.

Installation Notes

Installation requires a hand-operated or pneumatic rivet tool sized for 3/16 inch body diameter rivets. Verify hole diameter matches the rivet body specification before setting to ensure proper mandrel break and clamp force. Wear eye protection during installation, as mandrel tails are ejected under force. Follow applicable building and mechanical codes when using blind rivets in load-bearing or pressure-boundary assemblies.
