Hanson #4 Spiral Screw Extractor

Irwin Hanson #4 Spiral Screw Extractor removes broken studs, bolts, socket screws, and fittings. It features an aggressive left-hand spiral design for extra gripping power. The 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. It removes bolts and screws 9/32"-3/8", 1/8" NPT, 1/8" BSP, 8 mm-10 mm. It uses a 1/4" drill bit.
