3/8in Drive Stud Extractor for 1/4in–1/2in Rounded Bolts, Steel Alloy

The ESTINK 3/8in Drive Stud Extractor is a rugged, heat-treated alloy steel tool designed to rescue you from stubborn damaged or rounded studs. Sized for 1/4in–1/2in (6–12mm) fasteners and compatible with most 3/8in drive tools, this extractor handles exhaust manifolds, fuel plugs, and other hard-to-remove bolts with confidence. Its chrome-plated finish adds corrosion resistance, helping it hold up under demanding shop conditions.

Designed for real-world use, this auto-adjusting stud extractor grips damaged studs firmly and lets you work efficiently. Place the extractor on the stud, tighten the jaws by turning the bottom hex flat nut counterclockwise, and the jaws will clamp securely. With the stud gripped, turn counterclockwise to remove, then loosen in the clockwise direction. The tool works with hand tools, ratchets, or pneumatic impact wrenches (tools not included), making it a versatile addition to any toolbox.
