Hitachi Framing Nailer Piston Driver. This is a generic replacement driver with o-ring for the Hitachi NR83A, NR83A2, NR83A2(S) framing 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.
