Dependable Fasteners for Demanding Applications

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.

EXCEPTIONAL TORQUE STRENGTH is achieved as the insert’s knurled body expands FILLING THE HOLE.

AVOID STRESS FRACTURES of your material and prolong punch and die life by specifying a radius corner in your hex hole. This is possible when using the A-H Series radius hex body insert

QUALITY INSTALLATIONS even in variable thickness materials are assured by AVK’s spin/spin ARO pneumatic tools and our SPP™ pneumatic/hydraulic tools.

SUPERIOR THREAD STRENGTH is provided due to our internal rolled thread manufacturing process.

THREADS GAUGE before and after installation due to the increased cross-sectional thickness of the thread area. Thread dilation is prevented.

INVENTORY REDUCTION is possible because of the A-K Series’ wide grip range capacity. It is 2.5 times greater than conventional rivet nuts.

SUPERIOR CORROSION RESISTANCE is provided by our standard zinc/yellow dichromate finish (96 hrs. salt spray to white corrosion). For exceptional corrosion protection we offer a tin/zinc alloy finish.

AVAILABLE in steel from stock. Additional materials such as aluminum, brass and monel are available by special order. Contact AVK for details.
