Product Review
Aftermarket Hitachi Nailer Piston Driver. This is a generic replacement drivers with o-ring for the Hitachi NV83A, NV83A2 and NV83A3 guns. This comes with a patent pending locking mechanism which will not allow the driver to unscrew from the piston. Aluminum is crimped into the unilok grooves of the shaft to prevent unscrewing. Guaranteed never to unscrew.
