The conical washer teeth bite into the mating surface when torqued, resisting vibration loosening without a separate locking element. The washer diameter measures 5\/16 inches and the width across flats measures 7\/32 inches. This fastener is suited for electricians, panel builders, electronics assemblers, and mechanical technicians working with 4-40 threaded hardware in light-duty assemblies, enclosures, and control panels. Sold in a box quantity of 100 pieces per order increment.\u003c\/p\u003e\n\u003cp\u003eThis nut is used in applications requiring a compact, self-locking threaded fastener on 4-40 UNC thread forms. Typical scenarios include securing terminal blocks, small brackets, PCB standoffs, and enclosure hardware in electrical and light mechanical assemblies. The zinc plating provides baseline corrosion resistance for indoor and mildly protected environments. The minimum order quantity is 100 pieces, making this packaging appropriate for service stock, shop inventory, and production line use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated conical lock washer eliminates the need for a separate locking element\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard for compatibility with standard inch-series threaded hardware\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides corrosion resistance for indoor service environments\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch washer diameter suits compact fastening layouts\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch width across flats for standard hex driver tooling\u003c\/li\u003e\n  \u003cli\u003ePackaged in 100-piece increments for shop and production inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or service-stock hex nut for 4-40 UNC threaded assemblies in electrical enclosures, control panels, and light mechanical hardware applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians, panel builders, and mechanical assemblers using standard hex drivers or nut drivers sized for 7\/32 inch across flats. De-energize any assembly before installing or removing fasteners in live electrical enclosures per applicable NEC guidelines. Do not over-torque; the conical washer teeth engage at rated torque and excessive force can strip the 4-40 thread or flatten the locking teeth. Inspect mating surfaces for debris before installation to ensure proper washer engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: K-Lock Hex Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Washer Type\u003c\/strong\u003e: Conical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/32 inches\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 Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0017 pounds (per piece)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\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: HNCWI0-40-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690823516466,"sku":"HNCWI0-40-100BX","price":3210.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df6f8b8a24dfc911e6f880fd9fca5697.jpg?v=1788275757","url":"https:\/\/voomisupply.com\/products\/value-collection-hncwi0-40-100bx-4-40-k-lock-hex-nut-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
