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.
