Built to Grade L9 steel and finished with a cadmium dichromate coating, this nut delivers strong corrosion resistance alongside reliable prevailing-torque locking performance. The distorted thread profile creates mechanical interference when driven onto a bolt, maintaining clamp load without the need for separate locking hardware. At 0.58 inches tall with a 7\/8-inch width across the flats, this nut fits standard 9\/16-12 UNC threaded fasteners. It is installed by mechanics, millwrights, and maintenance technicians working on equipment assemblies that require vibration-resistant connections.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for heavy-duty industrial and mechanical applications where standard hex nuts may loosen under dynamic or vibratory loads. The 9\/16-12 UNC thread is a common size found in structural assemblies, machinery frames, agricultural equipment, and similar applications. The right-hand thread direction is standard for typical bolted connections. The cadmium dichromate finish provides additional protection against corrosion in moderate service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDistorted thread locking style provides prevailing-torque retention without additional locking hardware\u003c\/li\u003e\n  \u003cli\u003eGrade L9 steel construction for high-strength fastening performance\u003c\/li\u003e\n  \u003cli\u003eCadmium dichromate finish for corrosion resistance in moderate service environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch width across flats fits standard hex tooling\u003c\/li\u003e\n  \u003cli\u003eInch-system fastener conforming to UNC thread standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation hex lock nut for 9\/16-12 UNC threaded bolts and studs in industrial, mechanical, and structural assemblies requiring a prevailing-torque locking fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanics, millwrights, or maintenance personnel using standard hex tooling sized for a 7\/8-inch across-flats nut. Power down and de-energize any equipment before accessing fastener locations on live machinery. Distorted-thread lock nuts are designed for single use in critical applications and should not be reused after removal, as the locking torque diminishes with each installation cycle. Follow applicable equipment manufacturer torque guidelines and relevant industry standards for fastener assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Distorted Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: L9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Cadmium Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.58 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 446012PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703939727666,"sku":"446012PS","price":1157.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47b5c0c7005e1073cbe378fa7fd3a628.jpg?v=1788419578","url":"https:\/\/voomisupply.com\/products\/value-collection-446012ps-hex-lock-nut-9-16-12-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
