One-Time-Use Parts and Fasteners
What is a one-time-use part, and how do you determine if a fastener, clip, or part can be reused? These are questions that we are confronted within the collision industry quite a lot. The other big question is “Where do I find this information”?
As the I-CAR Repairability Technical Support (RTS) team researches OEMs for one-time-use part information, we are putting together a series of articles on how and where to locate this information for specific OEMs.
One-time-use fasteners/parts are specific items that cannot be reused after they have been loosened or removed. Types of one-time-use fasteners/parts include certain bolts, clips, trim, etc. They can even include stationary glass.
Most OEMs have at least one example of a one-time-use fastener/part. The reason it is only good for one use can vary. For example, torque-to-yield bolts are designed to stretch during the torquing process. These fasteners cannot be reused because of the excess amount of stress that was caused during installation. Some fasteners may have to be replaced due to a factory applied coating that prevents corrosion. In other cases, a part or fastener, such as a rivet, is simply impossible to remove without damaging it.
One-time-use parts and fasteners that appear to be uncompromised may look good but should not be reused. In addition, if new fasteners are supplied with a replacement part…use them.
Following OEM procedures, including the identification and use of one-time-use fasteners/parts, is important in order to help ensure a complete, safe, and quality repair.
