Installation hole size for the A-T Series Insert is determined by the parent material's thickness and density. The thicker the material the larger the hole required to allow full 360° installation swaging. The application should be tested before hole size is specified.
The A-T Series Insert is unique in that it can be installed into most any material above .030/,76 mm in thickness. As the A-T Series is installed, the threaded portion is completely swaged 360° into the sleeve portion and the hole. This permits the A-T Series to be used with Grade 8/metric 12.9 mating screws. The A-T Series Insert is installed using lightweight, hand held pneumatic tools that can be located at any position in your product's assembly sequence. The A-T Series Insert can be installed either prior to or after finish.
HOW IT WORKS FOR YOU
As the A-T Series Insert is installed, the threaded nut portion is drawn into the upper sleeve portion.As this occurs, a 360° swaging action takes place anchoring the A-T Series in the parent material.

I installed 12, 6-32 nutserts in 0.062 in wall, aluminum tubing to repair stripped threads. Worked great. Used nutsert tool to install these and it worked great also. Installed nutserts feel strong and give much more thread engagement. Nutsert protrudes a little bit above tubing surface when installed. I filed and polished them down to make them flush. This did not seem to degrade the installation.
Received as ordered. One of few companies that follow up with their customers. Will continue to do business with them.
Easy to install and quite strong.
I found a very small dab of JB weld in the middle outer dimple works wonders for filling in any irregularities in the hole. The JB weld ends up on both sides of the metal and squeezed into the hole. Might also help from any spinning in the future.
They are both quality blind nuts, but we do not have any data that compares the two. Nutserts are the more popular units, and that may be because of the shorter lip in the surface of the hole, and nurreled outer surface to help prevent the unit from spinning once installed.
Nutserts can be installed with AA-112 Hi torque tools, AAT916 expandable tools, or a AAT312A master nutsert kit. See Accessories.
All of the nutserts listed on this page are made of carbon steel.
These two nutserts will have lengths on approximately .375"
