Crescent® is a premier hand tool brand from Apex Tool Group, one of the largest hand tool manufacturers in the world. The Crescent Tool Company introduced the original adjustable wrench in the early 1900s, which in effect replaced an entire set of dedicated- size wrenches. It quickly became and continues to be one of the most essential tools in the toolbox. Today, the Crescent® line has expanded beyond adjustable wrenches to include a wide selection of pliers, ratcheting wrenches, screwdrivers and toolsets.
