Superior Parts SP 150744-3 Piston Driver – Premium US S7 Material, Replacement For Makita AN611 Coil Siding Nailer

About This Product

This Superior Parts piston driver is a top-notch replacement for the Makita AN611 coil siding nailer.

It's made from premium US-sourced aluminum with a hardness of 59 HRC, so it's tough enough to handle heavy-duty use and excessive wear without breaking down.

What really sets it apart is the UNI-LOK technology – the shaft grooves are hydraulically crimped to ensure that the piston driver absolutely never unscrews, even under extreme torque.

They've tested it up to 80 N-M (that's 59 ft-lbs) and it holds solid.
The threaded end is annealed (softened) to improve shock resistance, making it more ductile where it counts, while the shaft stays hard for durability.

It's a direct fit for the AN611 and comes with the o-ring included.

Tradesmen highly recommend these as a reliable alternative to OEM parts.

If your nailer's driver is worn out or broken, this is the fix.
Built tough, engineered smart, and backed by solid quality control.

You'll be back to nailing in no time with this installed.
