AMSUO 5-Piece Milled Screw Extractor Set (EXTP-5) — Bearing Steel, Coarse-Thread Reverse Spiral Flutes, No.1–No.5, High-Torque Grip for Broken Bolts & Studs

AMSUO 5-Piece Milled Screw Extractor Set (EXTP-5) — Bearing Steel, Coarse-Thread Reverse Spiral Flutes

Milled from bearing steel — built for higher torque, precise engagement and zero slip. Each extractor is milled as one piece rather than cut from a threaded blank, so the coarse reverse-spiral flutes hold their edge and bite deeper as turning force rises. The set runs from No.1 to No.5, covering the fastener range most workshops actually meet — from stripped screws up to seized studs and broken bolts. Supplied in a red translucent case with a moulded insert. Factory-direct from a 20-year precision-tools manufacturer with ISO 9001 / 14001 / 45001 triple-system certification.

What's in the Box

Item code: EXTP-5. Material: bearing steel, milled one-piece. Extractor range: No.1–No.5 (graduated). Flute: coarse-thread reverse (left-hand) spiral. Coating: bright finish. Packaging: red case with moulded insert.

Key Features

• Precision-milled from bearing steel — higher torque capacity than screw-type extractors
• High strength and toughness resist snapping in seized or hardened fasteners
• Coarse-thread reverse spiral flutes bite progressively as torque rises for a precise, non-slip grip
• Five graduated sizes (No.1–No.5) cover common broken-bolt, stud and stripped-screw jobs in one set
• Moulded insert keeps every extractor in place and the set upright on the bench

Recommended Applications

• Broken bolts, studs and screws in engines, machinery and equipment
• Automotive repair — manifold bolts, caliper bolts, cover and housing screws
• Plumbing, HVAC and industrial maintenance — seized and corroded fasteners
• Woodworking and furniture — stripped or snapped wood screws
• Farm, shop and fabrication repair, plus general DIY

How to Use

Center-punch the broken fastener, drill a pilot hole sized to the extractor, tap the extractor into the hole and turn counterclockwise. Apply steady pressure, keep the tool square, and always wear eye protection.

Quality & Certification

Produced in an ISO 9001 / 14001 / 45001 triple-certified facility. Every extractor is inspected before packing and supplied in retail-ready protective packaging.

FAQ

What material are these extractors made from? Bearing steel, milled as a single piece for higher torque and repeatable grip.

How do I choose the right size? Drill the largest pilot hole the broken fastener will accept, then start with the largest extractor that fits. Step down a size only if the extractor slips.

Will they grip hardened bolts? The coarse reverse-spiral flutes bite progressively as torque rises, which is what makes seized and hardened fasteners removable — drill an accurate pilot hole first.

Can I use them in a power drill? Yes — turn counterclockwise at low speed with light, steady pressure. A tap wrench gives the best control.
