Irwin Hanson Spiral Flute Screw Extractors - 534/524 Series

• Designed to remove broken studs, bolts, socket screws and fittings
• Aggressive left hand spiral design for extra gripping power
• Spiral flutes are designed to embed themselves deeper into the metal as you turn the tool, so as the fastener resistance increases, the extractor's grip increases
• Extractor size and recommended drill bit size are etched on each tool
