A-L Series

A-L Series Threaded Insert

The A-L Series Insert features a knurled body and large diameter-low profile head making it ideal for use in punched or drilled holes. It offers the highest all around strength characteristics and has been designed to be used with Grade 5 or Metric 8.8/9.8 mating screws. The A-L Series is AVK's most versatile performer.

The A-L 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-L Series can be installed either before or after finish.

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

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-L 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.

Various A-L Series Design Types
Open End OPEN END

The open end AL-Series is AVK's most versatile product.

Closed End CLOSED END

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

Sealed Head SEALED HEAD

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

Wedge Head WEDGE HEAD

The addition of wedges under the head provides even greater torque capability, especially in soft or thin materials, and is excellent for electrical grounding applications.
