Tangless Screw Thread Insert, also known as a tangless helicoil insert or tang-free threaded insert, is a specialized type of threaded insert used to reinforce or create threads in materials like metal, plastic, or composite materials. What distinguishes it from traditional wire thread inserts is the absence of a tang, which is a small tab or tangential protrusion found at the end of many standard wire thread inserts.
Tangless screw thread inserts find applications in industries such as aerospace, automotive, manufacturing, and machinery, where reliable threaded connections are critical. Their tangless design simplifies installation and reduces the risk of installation-related issues, making them a favored choice in many demanding applications.
