Spiral Flute Screw Extractors - 535/524 Series Set

Features: 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
