Powerbuilt Extension Bars – 3/8 In. Drive

The Powerbuilt 3/8 Inch Drive 10 Inch Extension is the perfect socket extension. It’s made from high-quality Chrome Vanadium steel with a mirror polished chrome plated finish for durability and long tool life. Extensions are perfect solution tools for when accessing hard-to-reach places like when working in and around engines, under the chassis, or any other jobs that require a longer reach in a tight space. Each extension features knurling on the center of the shaft for a secure grip to allow for quicker rotation when tightening or loosening fasteners. There is no need to worry about dropping sockets into narrow spaces; the Powerbuilt extensions also feature spring-loaded detent balls to help lock into and secure the sockets for worry-free retention.
