Made from high-speed steel (HSS), it delivers the hardness and heat resistance required for threading steel, stainless, and other ferrous metals at production speeds. The die features an adjustable design, allowing the technician to dial in thread fit by slightly opening or closing the die body with a set screw. Machinists, tool-and-die workers, and maintenance mechanics use this type of die for creating or restoring threaded fastener ends on small-diameter shafts and rods.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for applications requiring left-hand thread profiles, such as assemblies where counter-rotation would loosen a standard right-hand fastener. The 1-64 UNC designation indicates a 1 number size shaft diameter with 64 threads per inch, placing it in the fine-end range of unified coarse thread standards. Typical use cases include instrument hardware, specialty fasteners, and mechanical assemblies where left-hand thread engagement is a functional requirement. It fits standard round die holders sized for this die body diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for extended tool life and heat resistance during threading operations\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction for assemblies requiring reverse-thread engagement\u003c\/li\u003e\n  \u003cli\u003eAdjustable die body allows fine-tuning of thread fit and tolerance\u003c\/li\u003e\n  \u003cli\u003e1-64 UNC thread standard for small-diameter unified coarse thread applications\u003c\/li\u003e\n  \u003cli\u003eRound die form fits standard die stocks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use round die for standard die stocks and holders accepting this die body size in 1-64 UNC left-hand thread configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRound dies are installed and driven by a matching die stock; ensure the stock size matches the die body diameter before use. Secure the set screw on the die stock before beginning the threading pass, and apply appropriate cutting fluid to the workpiece to reduce friction and improve thread finish. The adjustable feature should be set and locked prior to threading to maintain consistent thread depth across the run. This tooling is typically used by machinists and maintenance trades in shop or field environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112805\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: 81931641\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698408718642,"sku":"81931641","price":30.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/289f6ce7d74e30c567fc3d9b29645992_1a97cd1e-31fc-4071-a269-f111d11ddcfc.jpg?v=1788362394","url":"https:\/\/voomisupply.com\/products\/value-collection-81931641-round-die-1-64-hss-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
