The Medium-Heavy Duty Rivet 250 Pack Red Flange Type Aluminum Mandrel from Allstar Performance is an essential fastening solution for automotive fabrication, restoration, and structural repairs. Whether you're building a custom frame, repairing body panels, or assembling chassis components, these aluminum mandrel rivets provide a permanent mechanical joint without welding or threading. Favored by professional mechanics, restoration shops, and performance builders, this 250-pack bulk quantity ensures you have sufficient fasteners for complete projects or shop inventory without frequent reordering.
Aluminum mandrel rivets work by drawing a mandrel (stem) through the rivet body using a pneumatic or manual rivet gun, causing the rivet to expand and create a permanent joint across multiple material layers. The red flange design features a larger head surface that distributes load evenly, reducing the risk of pull-through on thin sheet metal or composite materials commonly encountered in automotive bodywork. Aluminum construction keeps weight to a minimum—critical in performance and motorsport applications where every pound matters—while maintaining sufficient shear and tensile strength for structural fastening in non-critical load paths such as trim, brackets, and panel attachment.
Mechanics and fabricators benefit most from this bulk 250-pack when working on full restorations, custom builds, or maintaining shop stock for customer repairs. Installation requires a rivet gun compatible with mandrel-style fasteners; the rivet is inserted through pre-drilled or punched holes, and the tool pulls the mandrel, mushrooming the rivet body beneath the flange. These rivets excel in applications where vibration, temperature cycling, or corrosion resistance matter—including attaching body panels, securing interior trim, fastening fiberglass components, and assembling lightweight structural elements. Verify hole diameter matches rivet specifications before ordering, and store in a dry environment to maintain material integrity.
