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. The Pass-Thru™ sockets are a thin wall design. They replace the need for deep well sockets as they loosen and drive nuts on bolts of any length. The Pass Thru® sockets integrate into the GEARWRENCH GearRatchet™ handle, reducing overall height and increasing torque strength. The GEARWRENCH adapter allows for the use of standard sockets and drive tools.
