Ratcheting Combination Wrench SAE/Metric – 35720A-02. The Gearwrench 72 tooth ratcheting box end needs a minimal 5° to move fasteners vs. 30° for standard wrenches. Off-corner loading design on box end provides better grip and reduces fastener rounding. Pass-thru technology works down any length of threaded rod and long bolts. Thin head and beam provide greater access in confined work areas. Manufactured from alloy steel for better strength and longer tool life. The GEARWRENCH original ratcheting wrenches combine the speed of a ratchet with the access and control of a wrench. They offer the ease of 5 degrees of movement to turn fasteners, versus 30 degrees on standard combination wrenches. The small Ratcheting box end Head design enables access to tight spots where a ratchet won’t fit. The open end allows for easier access on tough to reach spots, making jobs go faster and easier.
