It cuts a 1-12 thread profile to the UNF standard in the left-hand direction, making it the correct tool when working with left-hand-threaded fasteners. At 1 inch thick, this die provides sufficient depth engagement for clean, accurate thread restoration. Constructed from carbon steel, it offers the hardness needed to chase threads on common fastener materials. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics reach for rethreading dies when field repairs require restoring fastener threads without full replacement.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for maintenance, repair, and overhaul work in commercial and industrial settings where left-hand-threaded fasteners are encountered. Typical applications include mechanical assemblies, equipment with reverse-rotation components, and any fastener installation where left-hand thread is specified to prevent loosening under torque. The hex outer profile allows it to be driven with a standard open-end wrench, ratchet, or die stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-12 UNF thread size restores fine-pitch left-hand external threads\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction for use on reverse-threaded fasteners\u003c\/li\u003e\n  \u003cli\u003e1 inch thickness provides solid engagement depth during rethreading\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction delivers the hardness required for thread chasing\u003c\/li\u003e\n  \u003cli\u003eHex outer profile compatible with standard wrenches and die stocks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rethreading die for use on 1-12 UNF left-hand external threaded fasteners in maintenance and repair applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis die is used by mechanics, pipefitters, and maintenance technicians for field thread restoration. Before use, secure the workpiece and apply cutting oil to the die and fastener to reduce friction and improve thread quality. Drive the die slowly in the left-hand direction, backing off periodically to clear chips. Inspect restored threads with a matching nut before returning the fastener to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 366-0642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723901927730,"sku":"366-0642","price":97.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9855dcb45aafea651a97ab19126fc03d_86283223-bde4-4697-b4cb-d5404d159465.jpg?v=1788609621","url":"https:\/\/voomisupply.com\/products\/value-collection-366-0642-hex-rethreading-die-1-12-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
