DIN302 High-Strength Solid Rivets for Aerospace
DIN302 solid rivets are permanent, high-shear fasteners for primary and secondary aircraft structures. The installed joint is formed through precise cold-forming, where the protruding shank is plastically deformed by a bucking bar to create a flush shop head, ensuring complete hole fill and uniform load transfer in shear-critical applications.

Material Specifications
Manufactured from aluminum alloys (e.g., 2117-T4, 7050-T73), titanium (Ti-6Al-4V), or corrosion-resistant steel per DIN 302 and EN 2877. These standards define head styles (universal, 100° countersunk), shank diameters, and length tolerances for aerodynamic surfaces.
Joint Mechanics
The joint's static strength is derived from shank expansion and shop head formation, with ultimate shear strength defined by material and temper (e.g., 165 MPa min. for 2117-T4). The cold-forming process work-hardens the rivet and induces compressive stresses around the hole, significantly improving fatigue life.
Aerospace Integration & Validation
Applied in airframe splices, skin-to-stringer, and rib attachments. Installation requires drilled holes to h7/H8 tolerance, calibrated pneumatic guns, and matched bucking bars. Validation includes shop head geometry inspection, go/no-go gauge checks, and periodic destructive drive-through testing for internal fill verification.
