AVK Fasteners - A-H Series Hex Insert

EXCEPTIONAL resistance to spinning in the panel is achieved as the A-H Series™ hex 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 trivalent finish (120 hrs. salt spray to white corrosion). For exceptional corrosion protection we offer a trivalent tin/zinc alloy finish.
AVAILABLE in Steel. Additional materials such as aluminum, brass and monel are available by special order.

SPINWALL TECHNOLOGY™

HOW HOLE FILL WORKS FOR YOU

As the A-H Series™ is installed, the radius cornered hex body expands FILLING THE HOLE. This feature provides exceptional torque strength and vibration resistance.

The installation tool then continues to install the insert forming a backside flange even in multiple or variable thickness materials — WITHOUT ADJUSTMENT.

Closed End

Thread area is enclosed eliminating leakage past the threads from either side of the application.

Sealed Head

PVC foam seal is bonded to the underside of the head and when installed provides a weathertight seal. Also available in closed end version.

Step 1

The operator 1/4 turns the AVK fastener on to the tool mandrel and places it into the hole. Operator then presses the top trigger on the tool and the AVK part installs.

Step 2

Once hole fill is complete, the AVK fastener forms its backside flange behind the parent material and the tool stalls.

Step 3

The operator reverses the tool and proceeds to attach the mating component using the appropriate mating hardware. The entire installation sequence of the AVK fastener takes 3 seconds or less.

Notes:

The operator can install the AVK fastener into two different material thickness’. This is the key benefit of the AVK System. You are able to install our products into single, variable or multiple thickness materials without tool adjustment.

During installation the AVK fastener expands within the hole Filling The Hole. This assures excellent spin out resistance and is a feature unique to AVK fasteners.

AVK fasteners are designed to be installed right on your assembly line either before or after paint or finish is applied to your product. This saves space and improves process flow.
