Recoil Tangless or Helicoil Tangfree or Helicoil Tangless Inserts are economical, helically-coiled fastening devices providing permanent, wear resistant screw threads which exceed the strength of most parent materials. Recoil Tangless Inserts or Helicoil Tangless inserts are made of cold-rolled stainless steel wire (AS7245), work-hardened to a tensile strength above 200,000 psi, and a hardness of Rc 43-50. The
finished surface (32 microinches) is exceedingly smooth, virtually eliminating friction-induced thread erosion.
Recoil Tangless Inserts or Helicoil Tangfree inserts are identical in form, fit, and function to the conventional tanged inserts. Tangless inserts are identical to tanged inserts in every way except for their method of
installation and removal, and they have the exact same procurement specification (NASM8846 for unified sizes and MA1565 for metric sizes).
Recoil Tangless Inserts or Helicoil Tangfree inserts are available in five nominal lengths (1D, 1.5D, 2D, 2.5D, & 3D). The nominal length is a
calculated value and cannot be measured in the free state; it is the actual installed length plus 1/2 a pitch. The nominal length is a multiple of the thread size, or of the insert nominal diameter (D).
Recoil Tangless Inserts or Helicoil Tangfree inserts have below advantages:
- FOD-Free Design: No tangs to break off, retrieve or lose.
- Approved for use on military programs by NASM8846, NAS1130, and NA0276.
- Cost Reduction: Significantly decreases installation and inspection time (savings of $0.15-$0.50 per hole based on customer studies).
- Bi-Directional design eliminates insert orientation requirements.
- Quick, non-destructive removal prevents damage to the parent material and the insert.

Recoil / Helicoil strongly recommends using Prewinder style hand tools for ALL manual installation of Recoil/ Helicoil Tangless
inserts. The prewinder compresses the insert allowing for easier and more consistent installation.
Recoil / Helicoil Removal Tools are insert specific.
Consider switching to Recoil / Helicoil Tangless inserts and never use a destructive tanged extraction tool again!
Tangless: The Tangless Recoil Removal Tool is unique in the helical coil screw thread insert industry. The
Recoil Tangless removal tool allows quick, non-destructive removal of Tangless inserts, preventing damage to the
parent material and expensive castings.
The Recoil / Helicoil Tangless removal tool simply threads into the installed insert, grabs the removal notch and threads the
insert out without damaging the internal STI threads or surface of the casting.
