SOCKET 21MM X 27.8MM 1/2' DRIVE CRV 12 POINT

Features

• 21 mm size — common metric for machinery and automotive fasteners.
• ½″ (12.7 mm) drive square — compatible with standard half-inch ratchets and torque tools.
• CR-V (Chromium-Vanadium) steel construction — durable and resistant to deformation during use.
• 12-point internal profile — provides enhanced bite and fit in limited-access fastener positions.

Benefits

• High torque readiness: The ½″ drive gives access to higher-torque applications where smaller drives might fail.
• Versatile fit: The 12-point design allows more angles of entry into fasteners—useful in tight spaces or where clear-view is limited.
• Durable investment: CR-V steel and precision machining make it a long-lasting addition to tool-kits.
• Lunchbox friendly: Great single socket backup for kits where every size counts for service technicians.

Extra Information

• Ensure your ratchet or breaker-bar is fully seated in the socket drive square before applying torque, to minimise risk of rounding the drive corners.
• For heavy or industrial-grade fasteners, use in combination with a full-size impact socket if torque exceeds standard hand-tool limits.
• Keep the socket clean and free of metal chips, grit or corrosion—especially within the 12-point internal edges—to preserve maximum contact and prevent rounding.

Specifications

Safety

• Wear eye protection when loosening or tightening fasteners — chips or particles may eject.
• Ensure the socket is fully engaged with the fastener before applying torque — avoid “half-fit” which can cause rounding.
• Do not use standard sockets on impact drivers unless rated for impact use — use dedicated impact sockets instead.
