It features a 3\/8-16 UNC thread with a 1-1\/2 inch length under head and is fully threaded along its entire shank. The integrated serrated flange distributes clamping load and bites into the mating surface to resist loosening under vibration. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, it provides corrosion resistance suitable for general-purpose indoor and light-duty outdoor applications. Trade professionals and assembly technicians use this fastener where a separate washer would be impractical or where anti-rotation resistance is needed at the bearing surface.\u003c\/p\u003e\u003cp\u003eThis serrated flange bolt is suited for residential and light commercial mechanical assemblies, equipment mounting, and general fabrication work. The 3\/8-16 UNC thread pattern is a widely used coarse-thread standard compatible with standard tapped holes and nuts of the same designation. The flange diameter ranges from 0.771 to 0.793 inches, providing a consistent bearing surface without a separate washer. It is appropriate for steel-to-steel, steel-to-bracket, and similar structural connections where vibration resistance is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n\u003cli\u003eFully threaded shank allows maximum thread engagement across the full 1-1\/2 inch length under head\u003c\/li\u003e\n\u003cli\u003eSerrated flange bites into mating surface to resist loosening under vibration without a separate lock washer\u003c\/li\u003e\n\u003cli\u003eFlange diameter of 0.771 to 0.793 inches distributes clamping load over a wider bearing area\u003c\/li\u003e\n\u003cli\u003eAISI C1022 Grade 2 steel construction balances strength and machinability for general-purpose fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and light-duty environmental exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC serrated flange bolt for general mechanical and structural fastening applications requiring a coarse-thread hex-drive fastener with an integrated flange.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using a hex wrench or socket of the appropriate drive size. Always ensure the mating thread is clean and free of debris before installation. Do not exceed the rated load for Grade 2 fasteners, and follow applicable mechanical or structural codes for the specific application. Inspect the serrated flange contact surface for proper seating after final torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\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\u003eFastener 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\u003eWeight\u003c\/strong\u003e: 1.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 3724MWW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708067381554,"sku":"3724MWW","price":4578.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3995e3881d4852b56804d7f8b7cf7807.jpg?v=1788443802","url":"https:\/\/voomisupply.com\/products\/value-collection-3724mww-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
