Socket 1/2" 27 mm GEKO T00142-27 — 27 mm hexagon socket for 1/2-inch drive

GEKO T00142-27 is a 27 mm hexagon socket designed for use with 1/2-inch (12.7 mm) drive tools. The chrome-finished socket accepts standard 27 mm hex fasteners and is compatible with ratchets, torque wrenches and extensions. Built to meet general mechanical and automotive workshop requirements, this socket provides a straightforward solution for tasks that demand a 27 mm tool in a 1/2" drive format.

Advantages

The chrome finish offers corrosion resistance and smooth surfaces for easier cleaning and long-term use. The 27 mm hex profile ensures secure engagement with matching fasteners to reduce rounding and slipping under torque. Compatibility with 1/2" drive tools allows use with common ratchets and torque wrenches, making the socket suitable for both disassembly and assembly operations where consistent drive interface is required.

Suitable for

• Mechanical assembly and disassembly of 27 mm hex fasteners
• Automotive maintenance and repair tasks requiring a 27 mm socket
• Workshop and field service use with 1/2" drive ratchets and extensions
• Use with torque wrenches where a 27 mm socket is specified

Key specifications

• Drive size: 1/2" (12.7 mm)
• Socket size: 27 mm hexagon
• Finish: chrome
• Intended connection: compatible with ratchets, torque wrenches and extensions
• Application area: mechanical, automotive and general maintenance

How to use

Select a 1/2" drive ratchet, breaker bar or torque wrench and attach the socket securely to the square drive. Place the 27 mm hex socket over the fastener, ensuring full engagement with the flats before applying torque. When using a torque wrench, set the required torque value and apply force smoothly until the wrench indicates the set value. After use, wipe the socket clean and store it in a tool rail or case to avoid corrosion and maintain fit accuracy.

Usage recommendations

Use the socket only with compatible 1/2" drive tools and avoid applying torque beyond the rated capacity of the socket or the fastener. Inspect the socket for wear or rounding before precision work and keep the chrome finish free of debris to maintain reliable engagement.
