The integrated serrated flange distributes clamping load across a wider surface area while the serrations bite into the mating material to resist loosening under dynamic loads. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this bolt features a 3\/8-16 UNC thread and is fully threaded along its 3\/4-inch length under head. The hex drive allows installation with standard hand or power tools. This fastener is appropriate for general-purpose industrial and mechanical applications where a separate lock washer would otherwise be required.\u003c\/p\u003e\n\u003cp\u003eSerrated flange bolts of this type are commonly used in light structural connections, equipment frames, HVAC unit housings, electrical enclosures, and general fabrication work. The fully threaded configuration suits shallow through-holes and short-grip applications. The zinc plating provides a corrosion barrier suitable for indoor or mildly protected outdoor environments. These fasteners are sold in multiples of 25 and are handled by millwrights, maintenance technicians, sheet metal workers, and general tradespeople during equipment assembly or field repair.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange locks against loosening under vibration without a separate washer\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC fully threaded, 3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eFlange diameter ranges from 0.771 to 0.793 inches for broad load distribution\u003c\/li\u003e\n  \u003cli\u003eAISI C1022 Grade 2 steel construction\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 3\/8-16 UNC serrated flange bolt suitable for use in standard inch-series tapped holes requiring a fully threaded fastener with an integrated locking flange.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized for a 3\/8-inch bolt head. Ensure the mating surface and tapped hole are clean and free of debris before driving the fastener. The serrated flange is intended for use against metal or hard surfaces only — do not install against soft materials such as plastic or rubber where the serrations cannot engage properly. Tighten to the torque specification appropriate for Grade 2 fasteners of this thread size as referenced in applicable mechanical standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.771 to 0.793 inches\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: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: AISI C1022\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 3712MWW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707789771058,"sku":"3712MWW","price":2897.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ca656e8c736c44ed8b4bf51cefa56a_78a4cba9-bb7e-44dd-b458-bfb131535281.jpg?v=1788442161","url":"https:\/\/voomisupply.com\/products\/value-collection-3712mww-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
