Sk 40921 Wobble Socket Extension 1/4 in Drive

Product Description

The SK 40921 is a 1/4 inch drive wobble socket extension designed for use in tight or angled workspaces where a rigid extension cannot make a clean connection. The wobble design allows the drive to pivot slightly off-axis while maintaining torque transfer, reducing the need to reposition the tool or the fastener. Finished in chrome plating for corrosion resistance and easy cleaning, this extension measures 1.5 inches in overall length. It weighs 0.04 pounds, making it a lightweight addition to any socket set. Technicians working in confined engine bays, panel enclosures, or equipment cabinets will find this extension a practical everyday tool.

This extension is suited for general mechanical and trade work where a 1/4 inch drive is the appropriate drive size. Common applications include electrical panel assembly, HVAC equipment service, light plumbing fixture work, and automotive or equipment maintenance. The short 1.5 inch length keeps the tool close to the work surface, which is especially useful when access depth is limited. It is intended for use with standard 1/4 inch drive ratchets, flex handles, and T-handles.

Key Features

• Wobble drive design allows off-axis engagement for fasteners in restricted or angled locations
• 1/4 inch drive size compatible with standard quarter-inch drive socket sets
• 1.5 inch overall length keeps the tool compact in shallow-access situations
• Chrome-plated finish resists corrosion and wipes clean easily
• Lightweight at 0.04 pounds for minimal fatigue during detailed work

Compatibility

Designed for use with standard 1/4 inch drive ratchets, handles, and sockets as a wobble-style extension in trade and mechanical service applications.

Installation Notes

This extension is installed and removed by hand as part of a 1/4 inch drive socket assembly. Ensure the drive connection is fully seated before applying torque to avoid rounding the drive or damaging the fastener. The wobble function is intended for moderate torque applications only — do not use impact drivers or apply excessive force through the extension. Power down or de-energize any equipment before accessing fasteners in electrical or HVAC panels.
