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.
