Manufactured from steel with a zinc clear finish for basic corrosion resistance, this nut follows the 1\/2-20 UNF thread standard. Measuring 3\/4 inches across the flats and 5\/16 inches in height, it is a low-profile jam nut intended for use as a locking or positioning fastener in mechanical assemblies. Installation requires a standard open-end or combination wrench sized to 3\/4 inches.\u003c\/p\u003e\n\u003cp\u003eThis jam nut is suited for mechanical, HVAC, plumbing support, and general industrial assembly work where a left-hand threaded 1\/2-20 UNF fastener is specified. It is appropriate for residential and light commercial applications requiring a steel, zinc-finished fastener in a jam nut profile. Sold in packages of 10, it is a practical stocking item for shops and service vehicles that encounter left-hand threaded assemblies regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction prevents loosening in counter-clockwise rotation applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread standard for precise, fine-pitch engagement\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc clear finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eLow-profile jam nut design at 5\/16 inches high\u003c\/li\u003e\n  \u003cli\u003e3\/4 inches across flats for standard wrench fitment\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 for bench stock and service inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or stocking jam nut for any mechanical assembly requiring a 1\/2-20 UNF left-hand threaded fastener in a hex jam nut profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand and tool by any qualified mechanic or trade professional. Verify thread direction before installation — left-hand nuts tighten counter-clockwise and loosen clockwise, opposite of standard fasteners. Use a 3\/4-inch open-end or combination wrench to seat and torque the nut. Ensure mating threaded rod or shaft is also left-hand threaded to avoid cross-threading damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Clear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\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: MPA996269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690698408242,"sku":"MPA996269","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3412989aff3cc28b62f03135cf8e896.jpg?v=1788274130","url":"https:\/\/voomisupply.com\/products\/value-collection-mpa996269-left-hand-hex-jam-nut-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
