Initial joint consisted of a standard machine screw into an oversize flanged weld nut with a stainless steel locking helicoil insert. The use of these joint components resulted in 12% of all model vehicles being repaired off-line due to cross threading.


The four standard machine screws, oversized flanged weld nuts and stainless steel locking helicoil inserts were replaced with four M12 DUO-TAPTITE CORFLEX-I fasteners, and 4 steel nuts.

Customer Benefit

Since DUO-TAPTITE fasteners form their own threads, all incidences of cross-threading were eliminated and even though the DUO-TAPTITE CORFLEX-I fasteners themselves were more expensive than the standard machine screws, the joint component cost was reduced by over $1.00 per vehicle. This was due to the elimination of the oversized flanged weld nuts, helicoil inserts, hand-starting of the fasteners and rectification costs, resulting in a minimum annualized savings of $600,000. The use of DUO-TAPTITE fasteners also improved ease of assembly, increased vibration resistance, provided 100% joint integrity, lowered the body frame assembly cost and provided more accurate jigging of the nut plate to the body frame.
