Senco EA0167 Piston Driver for FIP35

The Senco EA0167 Piston Driver is a high-quality aftermarket replacement part specifically designed for the Senco FinishPro 35 Finish Nailer. Crafted from aerospace-grade aluminum, this piston driver features a unique UNI-LOK technology that hydraulically crimps the grooves of the shaft, ensuring that the driver remains securely attached and never unscrews during use. The aluminum construction is heat-treated to enhance its strength and durability, making it capable of withstanding excessive wear and tear. Additionally, the threaded end of the driver is annealed to reduce hardness and improve shock resistance, which is crucial for maintaining performance under heavy usage. This piston driver is equipped with an O-ring and a patent-pending locking mechanism that guarantees a secure fit, preventing any unscrewing from the piston. With a Rockwell hardness rating between 56-59 HRC along the shaft, it can endure significant torque—up to 80 N-M (approximately 59 ft-lb)—before shearing off. Customers have reported high satisfaction with its functionality and fit, noting that it performs exceptionally well as a replacement part for their nailers. Overall, the Senco EA0167 Piston Driver is engineered for reliability and efficiency, making it an essential component for anyone using the FinishPro 35 Nailer.
