Thread Repair Kit 5/16"-18

The Powerbuilt 647954 kit provides helical inserts to restore damaged 5/16"-18 threads in automotive and general hardware applications. It supplies the inserts needed to bring stripped holes back to a usable condition.

Build Integration

The inserts install into existing tapped holes, letting you reuse original fastener locations without oversized bolts or welding. This approach preserves the component and keeps the original thread pitch intact.

Suitability

Technicians and DIYers fixing stripped 5/16"-18 threads in engine blocks, brackets or machinery will find the kit fits the task. Buyers needing other thread sizes or a complete tap-and-drill set should look elsewhere.
