The Snap-on Combination Ratcheting Wrench Sets, Nos. OXR704 and OXRM703, have a patented, ratcheting, gear-design that delivers up to 40 percent more torque and 95 percent greater cycle life over competitive wrenches, according the company. The zero-degree offset and uni-directional design are Snap-on features that deliver more power in less lateral space to help access and remove the most stubborn fasteners in tight work spaces. The 80-tooth ratcheting gear minimizes the swing arc needed to move fasteners in restricted spaces. With the Flank Drive wrenching system on the box-end, the 4-pc SAE OXR704 set and the 3-pc Metric OXRM703 set are able to generate up to 15 to 20 percent more turning power while minimizing the risk of tool or fastener damage.
