It features a 1.375-16 thread size with a 2C class of fit, a 1.5-inch overall length, 1.5-inch height, and a 0.5-inch thread engagement length. The left-hand thread direction requires counterclockwise rotation to engage, making it suited for applications where standard right-hand threading would self-loosen under operational torque or rotation. Machinists, millwrights, and mechanical assembly technicians typically specify and install this type of precision Acme nut in lead screw and power transmission assemblies.\u003c\/p\u003e\n\u003cp\u003eThis nut is used in precision linear motion systems, machine tool assemblies, actuators, and other mechanical drive applications where an Acme thread form is required. The bronze material provides natural lubricity and wear resistance against steel lead screws, making it a common choice in manual and low-speed powered feed mechanisms found in both industrial and commercial machinery. The left-hand thread orientation is critical for proper installation  -  verify thread direction before assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction for applications requiring reverse-thread engagement\u003c\/li\u003e\n  \u003cli\u003e1.375-16 Acme thread size with 2C class of fit for controlled clearance and smooth travel\u003c\/li\u003e\n  \u003cli\u003eBronze material offers inherent lubricity and resistance to wear against steel lead screws\u003c\/li\u003e\n  \u003cli\u003eRound body profile with 1.5-inch overall diameter and 1.5-inch height\u003c\/li\u003e\n  \u003cli\u003eSingle thread start for predictable linear advance per revolution\u003c\/li\u003e\n  \u003cli\u003e0.5-inch thread length provides focused thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision replacement or service Acme nut for left-hand threaded lead screw assemblies requiring a 1.375-16 thread size and 2C class of fit in bronze construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or millwright familiar with Acme thread systems and power transmission assemblies. De-energize and lock out all equipment before removing or installing lead screw components. Verify that the mating lead screw is also left-hand threaded before assembly  -  installing a left-hand nut on a right-hand screw will result in immediate thread damage. Apply appropriate thread lubricant to the lead screw before engagement to protect the bronze nut surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1.375-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Thread Starts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.554 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\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: KEYSTONE THREADED PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NQ016AC1F003865\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE THREADED PRODUCTS","offers":[{"title":"Default Title","offer_id":67911580647730,"sku":"NQ016AC1F003865","price":107.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d402a486097215fb92226aaf513ac9e_0440e113-2b78-4d53-a880-f9427d01fbe6.jpg?v=1791212779","url":"https:\/\/voomisupply.com\/products\/keystone-nq016ac1f003865-precision-acme-nut-bronze-lh","provider":"Voomi Supply","version":"1.0","type":"link"}
