It cuts a 1\/4-28 UNF right-hand thread profile and fits a standard 1-inch hex wrench or die stock for torque application. The die is machined from carbon steel, giving it the hardness needed to chase threads on common fastener materials including mild steel and stainless. This is a field and shop tool used by plumbers, HVAC technicians, electricians, and general maintenance trades whenever a fastener thread needs to be restored rather than replaced.\u003c\/p\u003e\n\u003cp\u003eThis rethreading die is suited for both residential and light commercial service work where a 1\/4-28 UNF thread specification is encountered. Typical applications include restoring threads on machine bolts, instrument fittings, and equipment fasteners that have been damaged by corrosion, cross-threading, or impact. The right-hand thread direction matches the standard fastener orientation used in the vast majority of trade and OEM assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF thread profile for restoring fine-pitch external threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard fastener orientation\u003c\/li\u003e\n  \u003cli\u003e1-inch hex outer body accepts common die stocks and wrenches\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides the hardness needed for thread chasing on typical fastener materials\u003c\/li\u003e\n  \u003cli\u003eCompact single-die form factor suits toolbox carry and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-inch hex die stocks.

Secure the workpiece or fasten in a vise before applying torque to the die stock to prevent movement. Apply cutting oil to the die and fastener prior to use to reduce heat and extend die life. Do not force the die over severely deformed threads in a single pass — back off periodically to clear chips.\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\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\u003ePackage Dimensions\u003c\/strong\u003e: 6.25 inches L x 1.75 inches W x 0.67 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51542310846770,"sku":"9423","price":16.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cf560403cc7032f3ce33f584bd24788_d64d6283-e88c-4658-bc0c-ca3bb4932a79.jpg?v=1785897733","url":"https:\/\/voomisupply.com\/products\/irwin-9423-hex-rethreading-die-1-4-28-unf-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
