Description

A barbed, large headed insert available in extra short lengths in a range of thread sizes from M2 to M10.

The Microbarb incorporates all the standard features of the Multisert range but provides the designer and production engineer with an insert suitable for pull through applications in thin section materials.

The design incorporates a larger head and barb diameter to provide increased bearing surfaces. For larger thread sizes the back of the head is chamfered to reduce the apparent projection. Maximum thread engagement is achieved by countersinking the limited thread length at only one end.

To provide optimum performance the plastic material section should be designed to be slightly in excess of the Microbarb under-head length. This ensures that upon assembly a clamp with the mating part is achieved, whilst limiting the compression of the plastic material to eliminate the effects of creep.

The Microbarb is ideal for use in vacuum formed, rotational moulded and fabricated components.
Product Features

The Microbarb Multisert has been designed with a larger head and barb diameter to provide increased bearing surfaces in thin section materials. The insert can be pressed-in cold or with heat and is primarily used in a pull through mode in thermoplastics, but it can be used in thermosets with a tensile strength of less than 100Mpa and some degree of resilience.
