Part # AES25P280PBZYR, Pre-Bulbed Threaded Insert

Designed for superior pullout resistance in plastics and thin sheet metal.
Pre-bulbed design requires less installation load.
Pre-bulbed inserts require less installation load than straight shank and require slightly larger mounting hole size.
Other materials available.

NOTE: The Atlas® spin-spin or spin-pull tool can be used to install pre-bulbed inserts. Material hardness will affect the published grip ranges. Trial installations of this product in your application are recommended. We will be happy to provide samples for this purpose.
