Structural foam inserts

Foamsert self tapping brass inserts from Tappex Thread Inserts provides a solution for structural foam materials where holes must be drilled and there is no `skin’ to improve pull out resistance, blind holes in laminated chip boards and where exceptional pull-out loading is required.

The insert is double ended with a coarse truncated external thread. It has three equidistant cutting flutes over the length of the external form providing effective cutting action at many points. This gives a balanced cutting load, which reduces `side thrust’ guaranteeing close axial alignment of the insert in the hole.
