Compatible with DF225C, CN65Z, QCND65, and CN565Z models, this precisionengineered piston driver is built to deliver consistent performance in demanding applications. Manufactured from aerospacegrade aluminum combined with US S7 steel, it offers exceptional strength, durability, and resistance to wear. Key Features and Benefits: Aerospacegrade aluminum construction ensures a lightweight yet robust build for longlasting performance. US S7 steel shaft provides durability and impact resistance, even under heavy operational load. UNILOK hydraulic crimp technology secures the piston driver to the shaft, preventing loosening or unscrewing during extended use. Heattreated aluminum body maintains strength under stress conditions and resists excessive wear. Threaded end is annealed for increased ductility, reducing brittleness and improving shock absorption. Tested to achieve Rockwell hardness of 5659 HRC along the shaft for balance of strength and toughness. Can withstand a torque load of up to 80 NM (59 ftlb) before aluminum shear, ensuring reliable endurance in force applications. Practical Applications: 1. Ideal for professional construction crews using compatible nailers for framing, decking, or heavyduty fastening projects where tool reliability is critical. 2. Suitable for industrial manufacturing environments requiring repetitive, speed fastening without risk of component failure. 3. Appropriate for and maintenance technicians needing dependable replacement parts to restore tool performance and reduce downtime. This piston driver is engineered for professionals who demand precision, durability, and consistent performance from their fastening tools. Designed to withstand repetitive use in impact situations, it delivers peace of mind and reliability when accuracy and strength matter most.
