Aluminium Inserts

As a general rule, aluminium inserts are mainly used for joining plastics. They are used to stiffen components (tube supports) or as the counterpart to a direct
fastening. With the appropriate choice of geometry and alloy they obtain outstanding fastening results. The benefits of aluminium inserts as metal-metal fastenings become evident, particularly for components that are subject to vibration stress or where operating temperatures are high.

The benefits of a trilobular cross-section

approx. 35 % greater torsional torques compared with round-knurled inserts
greater vibration resistance
permits greater core hole tolerances when press-fitting
