The ARROW RMA3/16 is a 3/16 inch diameter by 1/4 inch aluminum blind rivet designed to create strong, permanent, tamper-proof joints in light-duty and medium-duty assembly work. The rivet sets without access to the back side of the material, making it a fast, reliable fastening solution across a wide range of trade and field applications. Unlike threaded fasteners, it will not strip out or vibrate loose over time. HVAC technicians, sheet metal workers, and general contractors routinely reach for this style of rivet when speed and joint integrity matter on the job site.
The RMA3/16 is suited for joining sheet metal, aluminum, fabrics, plastics, and leather. Common applications include metal cabinets, aluminum doors and windows, metal fixtures, automotive panels, heating ducts, gutters, and downspouts. The aluminum construction makes it a natural match for aluminum substrates where galvanic compatibility is a concern. Each pack contains 15 rivets.
Designed for use with standard 3/16 inch blind rivet tools on sheet metal, aluminum panels, heating ducts, gutters, downspouts, metal cabinets, aluminum doors and windows, and similar light-gauge material assemblies.
Installation requires a hand-operated or pneumatic blind rivet tool sized for 3/16 inch mandrels. Drill the correct hole diameter through both layers of material before inserting the rivet. Insert the rivet fully, then actuate the tool until the mandrel snaps — inspect the set head on the accessible side to confirm full flare. Follow applicable sheet metal or mechanical codes for fastener spacing and edge distance when used in structural or HVAC duct assemblies.
