Snap-Open Ratcheting Box Wrenches


Open the jaws to fit around a fastener like an open-end wrench; close the jaws and the wrench acts like a ratcheting box wrench, allowing you to turn fasteners without removing and repositioning the tool. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.
