Why You'll Love It

Self-Adjusting 7–19mm Grip

Hundreds of spring-loaded internal pins move independently to match the shape of the fastener.

Simply press the socket onto the nut, bolt, hook, or other compatible object and the pins automatically adjust around it.

No need to constantly switch between multiple socket sizes.

Works With More Than Standard Bolts

The universal design can grip many common and irregular fastener shapes, including:

• Hex nuts and bolts
• Square nuts
• Wing nuts
• Eye bolts
• Hooks
• Tension screws
• Screw heads
• Irregularly shaped fasteners
• Many worn or difficult-to-grip fasteners

One compact socket can handle a wide range of everyday repair jobs.

3/8" Standard Drive

It can also be used with compatible power drills when paired with a 3/8" drill adapter.
