The WILLIAMS COMFORT PRODUCTS QZOM50A is a 50 MM open-end torque wrench head designed for precision fastening in professional trade applications. It features a Z-type shank measuring 0.990 inches and delivers a maximum torque output of 480 ft-lb, making it suitable for high-load bolting tasks. The head is sold as an individual unit and is intended for use with compatible torque wrench drive systems.
