Expansion Inserts
Expansion Inserts are an easy to assemble alternative to other types where a durable thread is required, but the high pull-out resistance of a self-tapping or heat/ultrasonic is not essential.
They are placed, by hand, into a hole of specified dimensions and it is the action of the screw on final assembly which locks the insert into place.
Expansion Inserts are available in a parallel (Series 81) and headed (Series 82) version and are stocked in brass
