Built from carbon steel, this die handles 1\/4-28 UNF left-hand threads, making it the correct tool when working on fasteners and fittings that use a reverse-thread configuration to prevent loosening under rotation. Machinists, mechanics, and trade technicians use rethreading dies as a fast field repair option when replacing a threaded component is impractical. The hex body allows a standard die stock or wrench to apply consistent torque during the chasing operation.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for maintenance and repair work in industrial, mechanical, and trade service settings where left-hand threaded fasteners appear on rotating assemblies, specialty fittings, or equipment designed to resist counter-rotation loosening. The 1\/4-28 UNF pitch is a fine-thread designation common in precision mechanical assemblies. It is appropriate for bench work and in-the-field thread restoration on external threaded stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF left-hand thread specification for reverse-thread fastener repair\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides the hardness needed for thread chasing on common fastener materials\u003c\/li\u003e\n  \u003cli\u003eHex body design accepts standard die stocks and wrenches for controlled torque application\u003c\/li\u003e\n  \u003cli\u003eSingle-piece die format — no additional components required for operation\u003c\/li\u003e\n  \u003cli\u003eFine-thread (UNF) pitch suited for precision assemblies requiring close thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a rethreading die for 1\/4-28 UNF left-hand external threads on bolts, studs, and threaded rod in mechanical and trade repair applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRethreading dies are used by machinists and trade technicians to restore damaged external threads; they are not for cutting new threads in hardened or specialty alloy stock. Secure the workpiece before beginning the chasing operation and apply appropriate cutting fluid to reduce heat and extend die life. Ensure the fastener or threaded component is fully de-energized, depressurized, and isolated from any load before performing thread restoration work. Inspect the restored thread with a matching nut or gauge after chasing to confirm full thread engagement before reassembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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\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: 366-0162\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709164224818,"sku":"366-0162","price":33.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04ff797cabafdb9cbe6e57cd725eb93a.jpg?v=1788452204","url":"https:\/\/voomisupply.com\/products\/value-collection-366-0162-hex-rethreading-die-1-4-28-lh-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
