Built from AISI C1022 Grade 2 steel with a zinc-plated finish, this bolt measures 2-3\/4 inches in length under the head and carries a 3\/8-16 UNC thread. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. It is driven with a standard hex wrench or socket. Trade professionals, maintenance crews, and fabricators use this type of fastener across a wide range of equipment assembly and repair tasks.\u003c\/p\u003e\n\u003cp\u003eThis serrated flange bolt is suited for general-purpose fastening in HVAC equipment panels, electrical enclosures, structural brackets, and mechanical assemblies where vibration resistance is a priority. The fully threaded shank allows engagement along the entire bolt length, making it useful in thin-material applications or wherever maximum thread engagement is needed. The zinc plating provides moderate corrosion resistance for indoor and light-duty outdoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC fully threaded shank — 2-3\/4 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSerrated flange resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFlange diameter 0.771 to 0.793 inches for broad clamping load distribution\u003c\/li\u003e\n  \u003cli\u003eAISI C1022 Grade 2 steel construction for standard-duty fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive — compatible with standard hex sockets and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC serrated flange bolt suitable for general mechanical assemblies, equipment panels, and structural connections requiring a hex-drive fastener with an integrated locking flange.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex socket or open-end wrench sized to the bolt head. Ensure the mating surface is clean and free of debris so the serrated flange seats fully and the anti-rotation teeth engage properly. Follow applicable torque guidelines from the equipment manufacturer or relevant standards for Grade 2 fasteners. Always de-energize or de-pressurize any equipment before disassembling fastened joints.\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: 2-3\/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\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\u003eDrive Type\u003c\/strong\u003e: Hex\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\u003eStandard\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\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 3744MWW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720963359026,"sku":"3744MWW","price":3313.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ca656e8c736c44ed8b4bf51cefa56a_5448722f-5923-4de1-9a17-5fbc9c5a0642.jpg?v=1788571529","url":"https:\/\/voomisupply.com\/products\/value-collection-3744mww-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
