GearWrench full-length deep socket with the Surface Drive off-corner loading geometry that contacts the flats of the fastener instead of the corners. The 6-point design grips hex bolts and nuts squarely and resists rounding on worn or rusted fasteners, while the 1/2" square drive handles the high-torque work where 3/8"-drive sockets give up.

• Drive size: 1/2" square
• Opening: 11/16" 6-point hex
• Configuration: Deep (full length, ~3" overall) for long studs and recessed nuts
• Surface Drive off-corner loading to reduce fastener rounding
• Chrome vanadium steel alloy, hardened and tempered for strength
• Full polish chrome finish for corrosion resistance and easy cleanup
• Meets ASME B107.5M dimensional and performance standards
• Permanent laser-etched size markings for easy identification in a tray

Fastener Match: Bolt and nut head 11/16" -- transmission mount bolts, automotive ball-joint nuts, and motorcycle rear axle hardware.

Deep vs Shallow: The deep configuration reaches recessed fasteners that a shallow socket cannot -- threaded studs sticking through nuts (U-bolts, leaf spring hangers, exhaust manifold studs), counterbored bolts in deep wells, and long shaft hardware. For ordinary flush nuts and bolt heads the shallow profile balances better and is faster to seat.

Drive Selection: The 1/2" drive carries the heavy-torque jobs in the 50-300 ft-lb range -- lug nuts, suspension bolts, U-bolts, and trailer hitch hardware. Step down to a 3/8"-drive deep socket for mid-torque accessory work in the engine bay and to a 1/4"-drive for precision interior and small-engine tasks.

Tip: This is a hand-tool chrome socket, not a black-oxide impact socket. Do not use it on a power impact wrench -- chrome plating is brittle at impact loads and can chip or shatter. Use a hand ratchet or a manual breaker bar; switch to GearWrench impact sockets (black phosphate finish) for cordless or pneumatic impact tools.
