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. - Spiral Flute Screw Extractor Set 1-6///brand_for_product_detail=Hanson,close_out=No,companydescription=Hanson - Made in the USA out of Global Components,condition=New,condition_google=new,cost=12.070000,countrymade=Made in the USA,country_flag=no_selection,featured=0,flag=no_selection,identifier_exists=0,instock=in stock,is_recurring=0,madeinusa=1,manufacture_country=United States,product_image_size=Default,product_page_type=Default,smart_campaign_bestsellers=Smart Campaign Bestsellers,square_product_image=https://square-production.s3.amazonaws.com/files/9c8b58fa8c9cb7361bd6fe9596c3292910534e99/original.jpeg,store_price=15.750000,sw_featured=No,sync_update_msg=Modified in Magento by harryepstein on 01/04/2017,url_path=spiral-flute-screw-extractor-set-1-6
