A-R Series

A-R Series Threaded Insert

The A-R Series™ threaded insert has been designed for use in plastics and thin gauge sheet metal applications where increased pull-out resistance is required.

The A-R Series features a PreSet™ slotted body design that when installed folds into four segments gripping the backside of the parent material. This design feature allows the A-R Series to be installed into single, variable or multiple thickness materials using AVK's ARO torque-stall pneumatic tools or AVK's SPP™ pneumatic/hydraulic tools.

Increased pull out in plastics and thin sheet metal.

Installs into variable thickness materials without tool adjustment.

Internal rolled threads make the A-R compatible with Grade 5 or Metric Class 8.8/9.8 screws.

All surfaces are plated for superior corrosion resistance.
