- REDUCED OVERALL LENGTH of the installed A-T Series Insert allows it to be used in limited clearance applications.
- QUALITY INSTALLATIONS even in variable thickness materials are assured by our spin/spin torque stall tools.
- INVENTORY REDUCTION is possible because one A-T Series™ Insert will work in any thickness material above .030/,76 mm.
- INSTALLS INTO MOST ANY MATERIAL with a thickness over .030/,76 mm.
- CAN BE USED WITH GRADE 8/METRIC CLASS 12.9 SCREWS due to the A-T Series™ high shear load capability.
- AVAILABLE in Steel from stock. Aluminum, Brass and Series 304 Stainless Steel are available by special order. Contact AVK for details.
JOINT DESIGN PRACTICES
AVK recommends that the mating part comes in contact with the head of the A-T Series™ Insert. If a gap or clearance hole exists between the mating part and the A-T Series™ Insert, the threaded nut portion may rotate or pull through the parent material.
Closed End
Thread area is enclosed eliminating leakage past the threads from either side of the application.

THE A-T SERIES™ INSERT
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.

- FINISH: The standard specified finishes for the A-T Series™ Insert are cadmium and tin. Alteration to these finishes will reduce performance.
- *THREAD CLASS: The A-T Series™ Insert internal threads are manufactured oversized to compensate for resulting thread portion shrinkage during the installation swaging process. They are not gaugeable prior to or after installation but will be compatible with Class 2A/3A or 6g screws after installation.
