Electronic torque wrenches

Stanley Proto has added to its line of Electronic torque wrenches three new fixed ratcheting head models. The wrenches accept standard Proto sockets, and come in ¼-, 3/8-, and ½-inch drive versions with torque ranges from 25 inch-pounds  (2.8 Nm) to 250 foot-pounds  (339 Nm). The wrenches are accurate to within 2 percent of indicated value in both directions (compared to 4 percenet clockwise and 6 percent counter clockwise on mechanical models). The fixed ratcheting head features a robust 24-tooth design with a 15-degree arc swing, an alloy steel drive gear for strength and durability, a low-profile design for easy access, and a reversing lever design to ease one-handed operation. The wrenches are ergonomically designed for user comfort and operate on 9-volt battteries. For more information visit www.stanleyproto.com or call (800) 800-TOOL.
