Tangless Thread Insert, also known as a tang-free or tailless thread insert, is a type of helical or coiled threaded insert used to reinforce or create threads in materials like metal, plastic, or composite materials. What sets it apart from traditional wire thread inserts is the absence of a tang. The tang is a small protrusion or tab found at the end of many standard wire thread inserts, and it is used to facilitate installation by tang break-off or removal after the insert is screwed into place.
Tangless thread inserts are used in a wide range of industries, including aerospace, automotive, manufacturing, and machinery, where reliable threaded connections are crucial. Their tangless design simplifies installation and reduces the potential for installation-related issues, making them a preferred choice in many applications.
