The Irwin Hanson 4 Spiral Screw Extractor is a specialized tool designed to remove broken studs, bolts, socket screws, and fittings. This extractor solves the problem of damaged or stuck fasteners with an aggressive left-hand spiral design that bites into the broken fastener and removes it effectively.
The tool’s spiral flutes are engineered to embed themselves progressively deeper into the metal as you apply turning force. This means that as the broken fastener resists removal, the extractor’s grip actually increases, making extraction more reliable. It works on fasteners ranging from 9/32 to 3/8 inch in diameter, plus metric equivalents (8–10 mm) and NPT and BSP pipe thread sizes. The extractor requires only a 1/4 inch drill bit to create the starter hole, keeping setup simple.
Features and Benefits
- Aggressive Left-Hand Spiral: The spiral design naturally rotates counter-clockwise, gripping the broken fastener with increasing force as you turn.
- Self-Embedding Flutes: Spiral flutes dig deeper into the fastener as resistance increases, ensuring secure grip under load.
- 1/4 Inch Drill Bit Compatible: Requires only a standard 1/4 inch drill bit to start the extraction process, no special equipment needed.
- Wide Size Range: Handles fasteners from 9/32 to 3/8 inch diameter, plus 8–10 mm metric, 1/8 inch NPT, and 1/8 inch BSP sizes.
- Multiple Applications: Works on machinery repairs, automotive fasteners, plumbing fixtures, and household equipment.
