The attachment points (weld nuts) were located within the car engine/suspension sub frame. The nut threads became clogged with heavy paint when the frame was dip painted. As the nut could not be replaced, or easily repaired, many sub-frames were scrapped. Additionally, pre-load was being achieved with paint in the threads. This allowed joint relaxation to occur. The bolts were highly loaded in service due to the input loading of the suspension roll stabilizing bar.
CORFLEX®-I TAPTITE® CA point fasteners were used in place of machine screws. Utilizing TAPTITE® CA fasteners eliminated the need for using pre-tapped weld nuts, eliminating any clogged threads during the dip painting of the sub frame. TAPTITE® fasteners form their own threads during installation and the addition of the CA point ensures the fastener will thread form through any weld splatter or paint present in the hole. Today, the new generation of TAPTITE® fasteners, TAPTITE 2000® CA fasteners, would be recommended for an even greater performance.
Utilizing CORFLEX®-I TAPTITE® CA point fasteners eliminated the tapping and paint clearing operation of the weld nuts. Savings were also achieved by eliminating scrap sub-frames due to the need to replace or repair the weld nuts and reduced warranty claims for re-torquing of the fasteners.
