These fasteners with threads as small as M1 install easily and permanently in a wide range of plastic materials from ABS to polycarbonate. They offer secure and reliable attachment, and a single mating screw completes the joining process.

microPEM (Type MSIB) inserts will install in either straight or tapered mounting holes and their symmetrical design saves time during production by eliminating any need for insert orientation prior to installation.

Installation is achieved by pressing the insert into a mounting hole using either ultrasonic insertion equipment or a thermal press.

When installed ultrasonically, the frictional heat caused by the vibration then melts the plastic surrounding the insert and, when the vibration ceases, the plastic solidifies to lock the insert into place.

Use of a thermal press will melt the plastic surrounding the insert to result in permanent installation.

The microPEM inserts are available in thread sizes M1 to M1.6 and in several lengths.
