Helicoil Inserts for Plastics?

Helicoil Inserts for Plastics?

Helicoil Inserts for Plastics?

(OP)
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 www.psminternational.com.

RE: Helicoil Inserts for Plastics?

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!

Agreed! Emhart Teknologies is a good company. We use the Dodge products in plastic and have never had a problem. Their website is www.emhart.com
