E-Z Fin™ (Finserts) Threaded Inserts for Plastic



E-Z Fin™ (Finserts) are a quick solution for adding machine threads to plastic materials. Each Finsert is designed with one, two or three OD fins that distribute stress over a greater surface area to minimize the possibility of cracking and protect against thread erosion. These brass threaded inserts for plastic are available with internal thread sizes ranging from #6 to 5/16.


Important Note: Hole size requirements may vary depending on a number of factors, including material and tools. We recommend that you test your particular application before ordering any E-Z Fin™ thread inserts for plastic. We gladly supply free samples.
