Built from carbon steel, this die handles the physical demands of rethreading work in shop or field environments. It is configured for 1-3\/8-12 UNF threads and features a left-hand thread direction, making it the correct tool for left-hand threaded applications where a standard right-hand die would not produce usable results. At 1 inch thick, the die provides adequate engagement length for clean thread restoration. Machinists, millwrights, and maintenance technicians are the primary users of this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis rethreading die is suited for maintenance and repair operations where existing left-hand UNF threads on bolts, rods, or mechanical components have been damaged, crossed, or corroded. It is used in manufacturing facilities, machine shops, and industrial maintenance settings where left-hand threaded hardware is specified for anti-loosening or directional load requirements. The 1-3\/8-12 UNF specification targets fine-pitch applications where thread integrity is critical to joint performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-12 UNF thread specification for fine-pitch left-hand thread restoration\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction for use on counter-threaded fasteners and components\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides durability for rethreading and chasing operations\u003c\/li\u003e\n  \u003cli\u003eHex outer profile accepts standard die stocks and wrenches for controlled torque application\u003c\/li\u003e\n  \u003cli\u003e1 inch thickness provides sufficient engagement for consistent thread form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard hex die stocks sized to accept a 1-3\/8-12 hex rethreading die.

Ensure the workpiece is secured in a vise or fixture before beginning thread chasing to prevent movement. Apply cutting oil to the die and workpiece to reduce heat and improve thread quality. Verify thread direction before use — this die cuts left-hand threads and will not produce correct results on standard right-hand threaded fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-12\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: 0.4 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: 366-1242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716160422194,"sku":"366-1242","price":134.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9855dcb45aafea651a97ab19126fc03d_3e24702c-c7d7-4cab-b28d-9c8291af7ece.jpg?v=1788522562","url":"https:\/\/voomisupply.com\/products\/value-collection-366-1242-hex-rethreading-die-1-3-8-12","provider":"Voomi Supply","version":"1.0","type":"link"}
