Socket 1/2" 11 mm GEKO T00142-11 — hexagonal hand socket for ratchet and wrench

Socket 1/2" 11 mm GEKO T00142-11 is a hexagonal hand socket designed for use with 1/2-inch drive ratchets and hand wrenches. It features an accurate 11 mm internal profile to engage hex-head bolts and nuts securely, allowing controlled torque transfer and reliable grip during tightening and loosening operations. The socket is intended for general automotive, mechanical and workshop tasks where a dependable hand socket is required. Pack quantity options are available as indicated by the manufacturer.

Advantages

The socket provides a precise fit to 11 mm fasteners, reducing rounding and wear on bolt heads. Its 1/2" drive compatibility ensures strong engagement with common ratchets and breaker bars, enabling higher torque application compared with smaller drive sizes. The hexagonal internal profile delivers even load distribution across the fastener faces, improving slippage resistance. The tool’s construction supports repeated use in workshop environments.

Suitable for

• Automotive repair and maintenance — wheel, engine and chassis fasteners
• Mechanical assembly and disassembly tasks
• General workshop and garage use for tightening and loosening nuts and bolts
• Professional and DIY applications requiring a reliable 11 mm socket

Key specifications

• Drive size: 1/2 inch
• Internal profile: 6-point (hexagonal)
• Nominal socket size: 11 mm
• Material: drop-forged steel (tool-grade construction)
• Finish: corrosion-resistant surface treatment
• Use type: hand socket for ratchet and wrench

How to use

Place the 11 mm socket onto the fastener head, ensuring full seating of the hex profile. Attach the socket to a compatible 1/2" drive ratchet, breaker bar or extension as required. Apply steady, controlled torque to tighten or loosen the fastener, reversing direction on the ratchet mechanism as needed. Inspect the socket and fastener for wear after use and store the socket in a clean, dry tool organizer.

Usage recommendations

Use the 1/2" drive socket with appropriately rated hand tools and avoid impact tools unless the socket is explicitly specified for impact use. Match the socket size precisely to the fastener to minimise rounding. Regularly check the socket for cracks, deformation or excessive wear and replace if any damage is found.
