A-H Series

A-H Series Threaded Insert

The A-H Series Insert features a radius corner hex body. When installed into a corresponding hex hole, the radius corners of the A-H Series Insert expand and fill the hole corners providing exceptional resistance to spinning in the panel. The A-H Series is designed to be used with Grade 5 or Metric Class 8.8/9.8 mating screws.

The A-H Series Insert can be installed using AVK's ARO brand pneumatic tools or AVK's SPP™ pneumatic/hydraulic tools. These tools can be located at any position on your assembly line. The A-H Series Insert can be installed either before or after finish.
