Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Net, Form And Pierce Repair
Failure to follow these recommendations could result in damage or failure to the part and the related parts.
Net, form and pierce is a manufacturing process which takes place during the original build of the vehicle. The original part will have a beveled platform that will decrease toward the fastener location mounting hole. Replacement parts in these areas may not include bevel (form) or fastener hole (pierce) and will need to be adapted for proper fit and finish.
The primary locations which may utilize net, form and pierce are:
- Fender reinforcement (at front end module mount)
- Fender tower mounts
- Hood hinge (lower half)
- Rear body header (liftgate hinge mounts)
- Strut tower (at upper control arm mount)
Shock tower is net, pierce only.
