Socket extension Wera 8794 A 1/4" drive — 1/4" output (6.3 mm)

The Wera 8794 A socket extension with a 1/4" drive and 1/4" (6.3 mm) output is a compact metal extension designed to connect a 1/4" wrench or driver to a socket while maintaining the same drive size. It provides a short, robust link that increases reach and access to recessed or obstructed fasteners without changing the tool interface. The extension is suitable for workshop, assembly and maintenance tasks where a direct connection between driver and socket is needed in tight spaces.

Advantages

The Wera 8794 A extension offers a solid, low-profile connection that preserves torque transmission and minimizes play between driver and socket. Its uniform 1/4" interface ensures compatibility with standard 1/4" sockets and drivers, allowing quick attachment and removal. The compact design reduces the risk of interference in confined work areas while providing reliable mechanical strength for everyday mechanical and assembly operations.

Suitable for

• Accessing recessed bolts and nuts in automotive and machinery maintenance
• Assembly work where a short extension is required to reach fasteners behind obstacles
• General workshop tasks requiring a 1/4" drive connection with extended reach

Key specifications

• Drive size: 1/4" (6.3 mm) input
• Output size: 1/4" (6.3 mm)
• Construction: metal extension for socket connection
• Profile: compact, low-profile length to fit confined spaces
• Compatibility: fits standard 1/4" sockets and drivers

How to use

Attach the 1/4" drive end of the extension to the driver or wrench until it locks or seats securely, then attach the compatible 1/4" socket to the output end. Use the combined tool assembly to reach and turn the fastener. Apply steady, controlled torque appropriate for the fastener and socket size. Remove the socket and extension by pulling them apart once the task is complete or when changing tools.

Usage recommendations

Use the extension within the rated torque limits of your 1/4" driver and sockets. Avoid using the extension as a lever or prying tool. Inspect for wear or deformation before use and replace if damaged. For high-torque applications, use appropriately rated adapters or larger drive sizes.
