Manufactured from aerospace grade aluminum
Designed with our UNI-LOK technology that hydraulically crimps the grooves of the shaft to ensure the piston driver never unscrews. The aluminum piston driver is heat treated to maintain strength and durability for excessive use and wear and tear.
Driver is annealed at the threaded end to lower the hardness and make the material more ductile for improved shock resistance. Rockwell Hardness Testing: Standard alloy drive hardness ranges between 56-59 HRC along the shaft.
All Superior Parts drivers are crimped at the aluminum base and can withstand a torque of 80 N-M (59ft-lb) before the aluminum shears off. Specifications: Material: Premium Grade Aluminum
Hardness: 59 HRC Compatible with N80CB/ N80C/ N80CB-1/ N80CB-HQ/ N80CB The Superior Parts SP N80157A is a generic replacement Piston Driver with O-Ring that excels in performance and durability that’s compatible with Bostich, N80CB/ N80C Nail Guns. Manufactured with our UNI-LOK technology that hydraulically crimps the grooves of the shaft to ensure the piston driver never unscrews. Drivers do not unscrew even at 80 N-M(59ft-lbs) during torque testing. The aluminum piston driver is heat treated to maintain strength and durability for excessive use and wear and tear.
