Stanley MR77C Heavy Duty Swivel Head Riveter

Product Description

The STANLEY MR77C is a heavy duty swivel head riveter designed for professional fastening applications across a wide range of trades. The swivel head design allows the tool to reach rivets at multiple angles without repositioning the workpiece, making it well suited for tight spaces and awkward joint locations. Weighing 1.91 pounds, it is compact enough for extended use on the job site. Licensed plumbers, HVAC installers, electricians, and sheet metal workers rely on tools like this for securing panels, brackets, ductwork flanges, and equipment enclosures where reliable blind riveting is required.

The MR77C is appropriate for light commercial and residential installation work where standard pop rivets are the specified fastener. It is commonly used when assembling sheet metal duct sections, electrical enclosures, equipment support brackets, and access panels. The swivel head makes it especially practical on production-style work where rivet orientation changes frequently across a single assembly.
