1/2" Drive 7" Extension Socket

This 1/2" drive extension socket measures 7 inches in length and features a friction ball retainer. It is engineered for use with impact tools according to current industrial specifications. The spring-loaded ball aligns with the socket retainer hole for secure engagement during heavy-duty work.

Friction Ball Retention Limits

The friction ball provides a positive mechanical lock that resists accidental release under vibration and torque. It is designed to function within the dimensional tolerances of standard 1/2" drive sockets and impact accessories. Excessive wear on the socket retainer groove or the ball mechanism itself will reduce holding force over time.

Compatibility Checks Before Ordering

Verify that your existing 1/2" drive sockets and impact wrench anvil accept a standard friction ball retainer. Confirm the 7-inch overall length suits the access depth required for your specific fastener locations. The tool is manufactured in Taiwan and supplied as a single unit.

Questions about this item

Is the 2247 the only length available or are there other extensions?

This listing covers the 2247 model which measures 22.86 cm long; other lengths would carry different model numbers and are not included here.

What does the 7-inch reach actually give me when the extension is on an impact gun?

The 22.86 cm length lets you access recessed bolts while keeping the impact tool body clear of surrounding components.

How does the 1/2-inch square drive with friction ball hold sockets under impact loads?

The spring-loaded ball seats in the socket retainer hole, providing positive retention that resists vibration from impact tools.
