Tangless insert are identical in form, fit, and function to conventional tanged inserts (CoilThread, Heli-Coil, Recoil, etc.), and install into the same STI tapped holes. However, unlike conventional tanged inserts, Tangless Inserts offer the following advantages:

• Tangless design means no tangs to break off, retrieve, or lose.
• Eliminates the need to purchase tang-break off tools, or rig tools to retrieve tangs from blind holes.
• Substantial installed cost savings over conventional tanged helically-coiled inserts (CoilThread, Heli-Coil, Recoil, etc.).
• NAS1130, NA0276 and NASM8846 Approval.
• FOD-free installation for increased flight safety.
• Quick and non-destructive insert removal and depth adjustment.
• Bi-Directional design, no need to orient the insert for installation.

Tangless Inserts have been thoroughly tested and scrutinized by independent testing facilities. The National Aerospace Standards Committee (NASC) published NAS1130 and NA0276 specifically for Tangless Inserts. In addition, Tangless inserts were added to NASM8846 (the procurement specification for helical coil screw thread inserts). Tangless Inserts are now the preferred design by many Aerospace and Defense companies.
