GearWrench 11mm standard metric socket with 3/8" drive square and 6-point design. Surface Drive technology applies torque to the flats of the fastener rather than the corners, reducing rounding on tight or partially-rounded heads. Made from chrome vanadium steel with full-polish chrome finish for corrosion resistance and easy cleaning. The knurled ring distinguishes metric from SAE sockets in the toolbox.

• Surface Drive off-corner loading reduces fastener rounding on hex bolts and nuts
• 6-point design grips fastener flats for maximum torque transfer on round/standard hex heads
• 3/8" drive square fits any standard 3/8" ratchet, breaker bar, or extension
• Chamfered opening guides the socket onto the fastener quickly
• Hard-stamped size marking resists wear from sustained use
• Knurled ring distinguishes metric from SAE at a glance
• Chrome vanadium alloy steel with full-polish chrome finish
• Meets or exceeds ASME B107.5M (metric hand-ratchet socket) specifications
• GearWrench full lifetime warranty against manufacturing defects

Application Tip (11mm): Less-common metric size used on M7 hardware (rare DIN size) and some older European specialty fasteners. Useful for vintage Italian and French automotive work where 10mm and 12mm sockets won't seat.

Tip: Use the 6-point socket on tight or partially-rounded fasteners where a 12-point would slip. Chrome (hand-tool) sockets like this one are designed for hand-ratchet use - for air or electric impact wrench work, switch to a black-oxide impact socket (chrome finish chips under impact loads). Step up to a 1/2" drive socket and longer breaker bar for high-torque applications like lug nuts, crankshaft pulley bolts, or large suspension fasteners.
