## Long description

Proxxon 23420 is a 21 mm socket head with a 1/2" square drive intended for tightening and loosening bolts and nuts. Designed to fit common 1/2" ratchets, torque wrenches and impact tools, this socket is suitable for general automotive, workshop and maintenance applications where a durable standard-size fastening tool is required.
Advantages
The socket head is manufactured to provide a precise 21 mm fit for hexagonal fasteners, reducing the risk of rounding. The 1/2" drive interface ensures compatibility with a wide range of hand and power drives, offering secure engagement and efficient torque transfer. Its steel construction delivers strength for repeated use under typical workshop loads while retaining a compact profile for access in moderately confined spaces.
Suitable for
Automotive repair and wheel or engine fasteners
General workshop maintenance and machinery assembly
Home and professional mechanical repair tasks
Key specifications
Nominal size: 21 mm across flats
Drive type: 1/2" (square drive)
Compatibility: fits standard 1/2" ratchets, torque wrenches and impact tools
Material: high-strength tool steel suitable for typical workshop torque
Finish: corrosion-resistant surface treatment for durability
How to use
Select the 21 mm socket when the bolt or nut head measures 21 mm across flats. Attach the socket to a 1/2" drive ratchet, torque wrench or compatible impact tool by pushing the square drive into the socket until it clicks or seats securely. For loosening or tightening, apply controlled torque appropriate to the fastener and application; when using a torque wrench, set the required torque value before applying force. Remove the socket by depressing the drive’s release mechanism (if present) or by pulling the socket off the square drive.
Usage recommendations
Inspect the socket and fastener for damage before use. Use correct torque settings for critical assemblies and avoid applying excessive force with manual tools. For impact-tool use, confirm the socket is rated for impact if the application requires repetitive high-torque blows; when in doubt, use tools and accessories explicitly specified by the tool manufacturer.
