The application of threaded inserts
Threaded Inserts are designed to improve the strength of assemblies by distributing forces from the fastener over a large area in the base material, thus increasing the load-bearing capability. For metals such as aluminum, this means full utilization of high-tensile-strength fasteners. In plastics, Threaded Inserts avoid wear and cold-flow problems encountered with thread-forming screws. Threaded Inserts offer both engineering and cost economies.
