* Captive nuts – there are two types of captive nuts available and their uses and applications differ. The first one is the clip on nut wherein he nut gets connected to the metal. These are mainly used in metal sheets which are very thin in nature and hence cannot be machine drilled; the holes created by these inserts can be easily removed and re-installed. The second type is the threaded nuts which are pressed into the holes in the materials to be moulded or joined.
* External Threaded inserts – they have threads both inside and outside and are generally threaded into pre-tapped holes.
* Helical inserts – threads made up of coiled wire used in repairing cylinder heads.
