Threaded Insert Pullout

Pull out comparison analysis of inserts compared with aluminum Mic6, aluminum 6061-T6 and A36 steel. Insert pull out was determined using a shear strength allowable of 2,000 psi (Epoxy adhesive).

To show comparison, a factor of safety was calculated comparing each material pull out strength with the strength derived for insert pull out. A factor of safety greater than 1 means that the traditional material experienced pull out (thread failure) before the insert.
