Fastening Alternatives to Adhesives or Rivets

SI® threaded inserts from Penn Engineering provide strong, reusable metal threads in plastics to allow for subsequent access to assemblies when required. These brass, stainless steel, or aluminum threaded inserts serve as practical alternatives to permanent joining methods, such as adhesives or rivets. Components can be removed and re-attached quickly and easily utilizing mating hardware.

Applications include computer and terminal boards; automotive and aerospace components; electronics, medical and communications equipment and others.

The product line includes ultrasonic/heat staking threaded inserts installed ultrasonically or with a thermal press; molded-in threaded inserts installed during the molding process and press-in threaded inserts installed by pressing them into pre-molded or drilled holes.

SI threaded inserts are available in a variety of types and in a wide range of unified and metric thread sizes. CAD drawings (in most formats) can be downloaded free from their website.
