Marson M40145 Open End Blind Rivet Button Head Steel 500 Pack

Product Description

The MARSON M40145 is an open end blind rivet with a button head profile, steel body, and steel mandrel. It is designed for one-sided fastening applications where access to the back of the workpiece is limited or impossible. The rivet features a 3/8-inch head diameter, a grip range of 0.032 to 0.125 inches, and a body diameter of 0.192 to 0.1875 inches. This package contains 500 rivets, making it suitable for production runs, job-site use, or shop stock. Plumbers, HVAC installers, electricians, and general trade contractors commonly use blind rivets for securing sheet metal, brackets, and ductwork assemblies.

The M40145 is well suited for light-gauge steel sheet metal fabrication, HVAC duct and panel attachment, electrical enclosure assembly, and general fastening tasks where a flush or low-profile head is acceptable. The button head style distributes clamping load across a broader bearing surface than a countersunk head, making it a practical choice for softer or thinner base materials. This rivet is intended for use with a standard pull-type blind rivet tool compatible with the body diameter.

Installation Notes

Blind rivets are installed by trade professionals using a hand-operated or pneumatic pull-type rivet tool. Drill the appropriate hole size through the base materials to match the rivet body diameter before insertion. Insert the rivet body into the hole, position the tool over the mandrel, and pull until the mandrel stem snaps. Do not attempt to reuse pulled rivets, as the mandrel and deformed body cannot be reset once set.
