Yato YT-06034 M10 HSS Screw Extractor for Broken Bolts and Studs

When a bolt snaps off flush or a screw head strips out, this Yato YT-06034 extractor gets you out of a jam. It's the one you reach for in the workshop or on a roadside repair to back out broken M10 fasteners without damaging surrounding threads. The left-hand spiral bites into the drilled hole and turns the remnant out as you apply reverse torque with a tap wrench or socket.

Key specifications

• Nominal size: M10 – for removing M10 screws, bolts, and studs
• Material: High-speed steel (HSS) with black oxide finish for corrosion resistance
• Design: Tapered multi-flute left-hand spiral for maximum grip
• Drive: Square drive end fits tap wrenches, adjustable wrenches, or sockets
• Recommended pilot drill: 6.4 mm
• Quantity: 1 piece

Why choose it

HSS construction gives this extractor the hardness to bite into tough steel fasteners without dulling quickly. The black oxide coating resists rust, so it stays ready in your toolbox for years. The aggressive left-hand flutes are engineered to dig in deeper as you turn, reducing the chance of slipping and rounding out the hole. It's a professional-grade tool that also suits serious DIYers.

Ideal use cases

• Removing broken exhaust manifold bolts on engines
• Extracting stripped screws from furniture or appliances
• Backing out seized studs from cylinder heads or blocks
• Recovering snapped bolts in agricultural or construction equipment
• Repairing threads in automotive, motorcycle, or marine applications

Good to know

Drill a precise pilot hole with a 6.4 mm bit before using the extractor. Apply steady, even pressure and avoid hammering or impacting the tool. For best results, use a tap wrench or a socket that fits the square drive snugly. Keep the extractor lightly oiled when stored to maintain its finish.
