Nutserts

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 Thread Size .030-.090 Mat.
