Inserts & Studs

Alcoa Fastening Systems has over 50 years of practical experience in the making of threaded inserts and studs, and offers the broadest selection available to serve the needs of the aerospace, industrial and automotive markets.
Alcoa Fastening Systems inserts and studs are available in both unified and metric sizes, and meet a variety of international standards. The parts are manufactured using a wide variety
of materials including corrosion and heat-resistant steels, carbon and alloy steels, titanium, and Inconel®. These high quality fasteners have become industry standards and individualized solutions to unique design problems. In addition, we offer tools for hole preparation, installation, and removal of our wide range of inserts and stud products.

Keenserts® inserts and studs are designed to provide high resistance to torque-out and pull-out loads. Pre-assembled keys are driven down through the threads of the parent material to
mechanically lock the fasteners into place. The inserts are available with freerunning threads or with various types of locking devices including deformed threads, Vespel™ insert, and beam lock. The studs provide a nut-end thread designed to transfer high axial loads into weak base materials. The stud or keyed end is installed into the parent material, thus eliminating the need for removing or replacing a bolt.

Kelox® inserts and studs are high performance threaded products that typically require smaller diameter installation holes than other solid bushing inserts and studs. This translates into overall reduced boss sizes and weight savings. The Kelox® fasteners incorporate a pair of self-broaching keys joined by an integral ring that facilitates the driving of the keys into the structure.

Ring Locked inserts, studs and size-on-size have superior torsional resistance in both hard and soft parent materials. Inserts are available with locking and nonlocking threads.

Slimsert™ inserts have a thin cross section, which is ideal for installation into applications requiring minimum boss configurations. This allows for reduced casting weight while adding strength. The upper end of the insert is swaged into the counterbore wall of the parent material and locks it into place.

Delron® inserts are used primarily to provide a hard mounting point in sandwich structure panels. Structural type inserts offer maximum shear and column strength by gripping and supporting the face sheets from within the core area of the sandwich panel. Potted in inserts are mounted through a single hole in the panel and resist shear and tension through a knurled flange on the body where potting compound flows.
