- VIRTUALLY FLUSH INSTALLATIONSÂ achieved without special hole preparation due to A-K Seriesâ„¢ minimal head profile.
- EXCEPTIONAL TORQUE STRENGTH is achieved as the insert’s knurled body expands FILLING THE HOLE.
- QUALITY INSTALLATIONS even invariable 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 Seriesâ„¢ 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.
