Powerbuilt 640846 Extension Bar Set

This three-piece set provides 1/2-inch drive extension bars for reaching fasteners in confined spaces. It is built for professional mechanics and serious home users who need reliable access on automotive and heavy-equipment jobs.

Suited for deep-reach bolting work

Technicians who regularly service engine bays, suspension components or transmission housings will find the extra length useful. Buyers who only need a single fixed length or who work exclusively with smaller drive sizes should look at something else.

1/2-inch square drive compatibility

Every bar in the set matches the standard 1/2-inch drive profile used on most heavy-duty ratchets and impact sockets. Confirm that your existing tools share this drive size before purchasing.
