Accepted Answer

The quick-release mechanism lets you rapidly change sockets with one hand, improving workflow and reducing downtime during fastener work.

Question 6

How does the wobble extension help in reaching fasteners?

Accepted Answer

The wobble extension provides a bit of flex and extra reach, allowing you to access fasteners that are in tight or awkward positions without compromising torque.
