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.
360°SWAGING 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.
NUTSERT HOLE SIZE / MATERIAL
THICKNESS CHART
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
