Self Tapping Inserts | SERIES 10

The course external thread of SPIROL's Self-Tapping Insert forms an internal thread within a molded or pre-drilled hole during the installation process into a plastic assembly.  SPIROL Series 10 Self-Tapping Inserts are thread forming Inserts best suited for softer thermoplastics or thermosets.
 
Self-Tapping Inserts provide the best pull-out resistance for a post-mold installed Insert, yet generally cost more than their post-mold counterparts. The external threads are designed with a thin profile to minimize induced stress in the plastic and have a relative coarse pitch to provide the maximum plastic shear surface to resist pull-out.
 
SPIROL’s Series 10 Self-Tapping Insert is a thread-forming Insert designed for use in soft, flexible thermoplastics and thermosets. Series 10 Inserts are available in thread sizes ranging from M3 (4-40) up to M6 (1/4-20).
