Threaded inserts are a great option for fastening thermoplastic parts. With inserts, parts can be safely and securely fastened using bolts, which means they can be easily disassembled and reassembled over and over again. When fastening with screws driven directly into plastic, there is a risk of creating crossed or stripped threads every time the parts are rejoined.
An additional benefit is high load-carrying capability. Inserts are generally twice the diameter of a screw, which increases the shear surface fourfold.
