The Pass-Thru socket and GearRatchet ratchet system by GEARWRENCH was designed to improve productivity and access on every job. The GearRatchet ratchets need as little as 5° to move fasteners vs. 30° for standard wrenches and are 40% stronger than standard ratchets by eliminating the drive tang. The ratchets are up to 50% thinner than standard ratchets providing superior access to even the most hard-to-reach fasteners.
