This Auveco system gives the designer the option to design for blind or open applications, eliminating and simplifying their design problems. Our system provides a cost-saving method of installing clean, load-bearing steel threads in castings, fiberglass, fiberboard, plastics, wood or almost any ductile material more than .030 thick. A simple hand tool installs the Nutsert, it is ready for use in seconds and no finishing is required after installation. Auveco Nutsert's advanced design offers unlimited grip range in a minimum of sizes. Inventory is minimized to one body dimension per thread size; ideally suited for blind, buried and through holes. The ingenious taper-lock principle locks-in the Nutsert preventing spin or twist; installs in flat or curved surfaces and is self-tightening with repeated use. The unique design of the installation tool eliminates marring of the parent material surface.
