This one-piece fastener combines a standard hex nut with a serrated external tooth washer that bites into the mating surface under torque, resisting loosening from vibration and dynamic loads. The zinc plating provides a baseline level of corrosion resistance for general indoor and light outdoor applications. Electricians, plumbers, HVAC technicians, and millwrights commonly use K-Lock nuts wherever a separate lock washer would be impractical or where assembly speed matters. Each nut weighs approximately 0.017 pounds.\u003c\/p\u003e\u003cp\u003eK-Lock hex nuts in 3\/8-16 UNC thread are widely used in mechanical assemblies, electrical panel work, equipment mounting, and light structural connections. The 3\/8-16 thread designation indicates a 3\/8-inch nominal diameter with 16 threads per inch, conforming to the Unified National Coarse thread standard. The washer diameter measures 57\/64 inches and the width across flats measures 9\/16 inches, making these compatible with standard 9\/16-inch hex drivers and wrenches. This SKU is sold in a minimum order quantity of 100 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIntegrated external tooth lock washer eliminates the need for a separate lock washer during assembly\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread standard for broad compatibility with standard fastener applications\u003c\/li\u003e\n\u003cli\u003eZinc plating provides corrosion resistance for general-purpose use\u003c\/li\u003e\n\u003cli\u003e9\/16-inch width across flats fits standard hex sockets and wrenches\u003c\/li\u003e\n\u003cli\u003e57\/64-inch washer diameter for adequate bearing surface on typical mating materials\u003c\/li\u003e\n\u003cli\u003eSold in quantities of 100 for high-volume assembly and maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or assembly fastener for any application using 3\/8-16 UNC threaded hardware where a locking hex nut with an external tooth washer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson following applicable mechanical and electrical codes. Always de-energize and lock out equipment before replacing or installing fasteners in electrical enclosures or live mechanical assemblies. Use a calibrated torque wrench and follow the torque specifications provided by the equipment manufacturer for the specific application. Do not reuse K-Lock nuts that show deformed or flattened lock teeth, as clamping effectiveness will be reduced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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 Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Washer Type\u003c\/strong\u003e: External Tooth\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\u003eWasher Diameter\u003c\/strong\u003e: 57\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: KEPI0370-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723525783858,"sku":"KEPI0370-100BX","price":3742.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/850f2ca431d058d113dbe59a97b6f2df.jpg?v=1788605822","url":"https:\/\/voomisupply.com\/products\/value-collection-kepi0370-100bx-k-lock-hex-nut-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
