預滾珠螺紋嵌件

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.
