Wire Thread Insert

Spiralock (Madison Heights, WI) has introduced its 2-56 Drive Notch™ (DN™) tang-free wire thread insert. Spiralock’s Drive Notch inserts feature a patented 30-degree “wedge” ramp formed into a 5-sided wire. The components also include self-loosening, shearing, stripping, binding, and reusability capabilities. With no tangs to remove, the DN inserts reduce the possibility of loose tangs short-circuiting or causing foreign object damage. They also prevent harm to expensive castings caused by invasive tang removal techniques.
