1/2-Inch Drive Wobble Extension Bar, 250mm Length, Chrome-Plated

Brief Overview

This 1/2-inch drive wobble extension bar extends your reach to fasteners in confined or angled positions without sacrificing drive integrity. The spring-loaded detent ball keeps sockets firmly seated during use, while the wobble design allows up to 15° angular deflection for those tight access points where rigid bars won't fit. Chrome-vanadium steel construction and bright chrome plating deliver durability and corrosion resistance in demanding shop environments.

For mechanics working with multiple drive sizes, consider complementary tools like compact wobble extensions for smaller drives or longer 600mm configurations for maximum reach applications.

Why This Works for Your Shop

Efficient Access: The wobble function eliminates the need for multiple extension bars in your inventory. One tool handles both straight and angled bolt removal, reducing setup time and keeping technician frustration low.

Stock Control: At 250mm, this length covers the "sweet spot" for most underhood work without the excessive weight or handling difficulty of longer bars. Pair it with shorter 75mm options for precision work in tight engine bays.

Resale Margin: Wobble extensions command a premium over rigid bars due to their specialized function. Professional mechanics understand the value—stock confidence is high, and turnover is reliable.

Durability Sells: Chrome-vanadium steel is industry-standard for impact-rated tools. The bright chrome finish signals quality to your customers and holds up against shop floor abuse.
