Rivetking 34257 Open End Blind Rivet 1/4 in Aluminum

Product Description

The RIVETKING 34257 is an open end blind rivet with an aluminum body and aluminum mandrel, designed for fast, single-side fastening in sheet metal, HVAC ductwork, enclosures, and light structural assemblies. The 1/4 inch body diameter and 1/4 inch head diameter deliver a secure, flush-style installation across a grip range of 1/8 to 3/8 inch. The length under head measures 1 and 1/64 inches. This rivet is a standard trade fastener installed by HVAC technicians, sheet metal workers, electricians, and general contractors wherever a blind fastening solution is required without access to the back side of the work surface.

The 34257 rivet is suited for residential and light commercial applications including HVAC duct assembly, electrical enclosures, equipment panels, and general sheet metal fabrication. Its all-aluminum construction makes it appropriate for use in corrosion-sensitive environments where dissimilar-metal reactions with steel fasteners would be a concern. Packaged in quantities of 250 per package, this rivet supports ongoing service and fabrication work without frequent reordering.

Installation Notes

Installation requires a rivet gun or pneumatic blind rivet tool sized for a 1/4 inch body diameter. Match the drill or punch hole diameter to the rivet body diameter before insertion. Ensure material stack thickness falls within the 1/8 to 3/8 inch grip range for a proper set. Aluminum mandrel stems should be collected and disposed of safely to avoid debris hazards in electrical or mechanical equipment.
