3/8 Drive 14 mm Stripped Bolt Extractor

Large-diameter studs on cylinder heads, turbo housings, and suspension mounts carry heavy clamping loads and suffer years of heat cycling and corrosion. When one snaps or seizes, removing it without damaging the parent casting demands a tool that fits the fastener exactly.

This 14 mm extraction tool delivers that precise fit. An internal gripping mechanism bites into the exposed stud and locks progressively tighter with every degree of rotation. Attach it to any 3/8 inch drive ratchet or breaker bar, apply steady force, and the tool holds while the stud turns free. No welding, no drilling, and no risk to the threads in the bore.

The 3/8 inch drive interface accepts every ratchet and breaker bar you already own. For heavily seized large-diameter studs, a long-handle breaker bar gives you the mechanical advantage to break the corrosion bond. In tighter spaces, a flex-head ratchet lets you work at an angle without losing engagement.

Sold individually so you pay only for the size your job requires. Technicians who work on the same engine family week after week can stock the specific sizes they need on their own cart, keeping the right tool within arm's reach. When a piece from an existing multi-size kit wears out, a single replacement restores the set without repurchasing every size.
