Abstract: This report presents: (1) fatigue data for 7075-T73 aluminum alloy plate containing threaded inserts; (2) the results of tests for determining the tensile load required to pull threaded insert out of the parent material; (3) the torque required to lock and unlock a bolt threaded into the insert and; (4) the susceptibility of the insert to corrosion when threaded into the parent material and exposed to a corrosive media. The types of threaded inserts evaluated consisted of solid wall bushings, helical coils, and the solid wall self-tapping bushings.
