The DURODYNE ss44d is a hollow-body steel blind rivet assembled onto a solid steel mandrel, sold in a pack of 1000. Blind rivets — sometimes called pop rivets — are mechanical fasteners used to join materials from one side when the back side is inaccessible. The ss44d measures 0.125 inches in diameter and is manufactured to strict quality control standards. The hollow-body and mandrel construction allows a single technician or installer to complete the joint without access to the reverse face of the workpiece. These are a standard fastener for sheet metal, ductwork, enclosures, and light structural assemblies across multiple trades.
The ss44d is suited for residential and light commercial applications where a 0.125-inch steel rivet is the specified fastener. Common installation scenarios include HVAC ductwork fabrication, electrical enclosure assembly, sheet metal panel joining, and general mechanical assembly where a permanent, vibration-resistant fastener is required. The all-steel body and mandrel make this rivet appropriate for applications that need a strong, durable connection in metal-to-metal or metal-to-substrate joints.
Designed as an OEM-style mechanical fastener for use in standard 0.125-inch rivet applications across HVAC, electrical, plumbing, and general sheet metal fabrication work.
Installation requires a standard 0.125-inch blind rivet tool or pneumatic rivet gun matched to this rivet diameter. Ensure the substrate hole is drilled or punched clean and is sized to match the rivet body diameter before setting. De-energize or shut off any associated systems before performing fastener work on live panels or ductwork. Discard spent mandrels safely, as they are ejected during the setting process.
