## Long description

Hex socket 21 mm with 1/2" drive by GEKO (model T00142-21) is a single-piece metal socket designed for use with 1/2-inch ratchets and torque wrenches to tighten or loosen 21 mm hex fasteners. The socket features a hexagonal internal profile that fits standard 21 mm nuts and bolts and a 1/2" square recess for secure connection to compatible drive tools. It is intended for repetitive mechanical work and comes packaged in multi-piece lots as specified by the seller.
Advantages
The GEKO 21 mm socket is manufactured as a one-piece design to provide consistent geometric accuracy and resistance to deformation under torque. Its 1/2" drive interface ensures compatibility with a wide range of ratchets, breaker bars and torque wrenches commonly used in automotive and industrial maintenance. The socket’s solid construction supports stable contact with fastener flats, reducing the risk of rounding or slipping during tightening or loosening operations.
Suitable for
Automotive repair and maintenance tasks involving 21 mm nuts and bolts
Mechanical assembly and disassembly in workshops and garages
General repair work on machinery, frames and equipment with 21 mm fasteners
Use with 1/2" ratchets, breaker bars and torque wrenches for controlled torque application
Key specifications
Drive size: 1/2 inch (square recess for drive tool)
Socket size: 21 mm across flats (hexagonal internal profile)
Construction: single-piece metal socket for strength and durability
Compatibility: fits standard 21 mm hex fasteners and common 1/2" drive tools
Typical packaging: multi-piece lots (quantities such as 10 or 100 depending on seller configuration)
How to use
Select a 1/2" drive ratchet, breaker bar or torque wrench and insert its square drive into the socket’s 1/2" recess until it seats securely. Place the hex end of the socket over the 21 mm fastener, ensuring full engagement on the flats. Apply torque evenly and avoid sudden impacts; when using a torque wrench, set the required torque value and apply force until the wrench indicates the set value. After use, wipe the socket clean, inspect for wear or rounding, and store in a suitable tool organizer.
Usage recommendations
Use the socket with the correct 1/2" drive tool and appropriate torque settings for the fastener to prevent damage. Avoid using damaged or heavily worn sockets and do not use the socket on rounded or compromised fasteners. For high-torque applications, confirm that both the drive tool and socket are rated for the intended load.
