Helicoil Inserts for Plastics? 2

[miner00]

A vendor of mine is recommending that we use helicoil inserts for a threaded hole in a part made out of Delrin. Most of the information that I have suggests that brass inserts are better for plastic materials. Does anyone have experience with this or know of a good resource?

Thanks for any suggestions.

Threaded inserts, such as the brass-type that you mentioned, would be a better fit than the helicoil-type for threading into plastic. PSM is a good manufacturer of inserts; their website is

An even better supplier of inserts for plastics is Emhart Teknologies, located in Danbury, CT. They make both the Heli-Coil and the Dodge line of inserts for plastics which can be obtained in 360 brass, steel, aluminium and stainless steel. Worked with them on several applications, great company!
