It features a 5\/16-18 UNC thread form with a 2-inch length under head and a hex drive head. The integrated serrated flange spans 0.686 to 0.706 inches in diameter, providing a built-in locking surface that resists loosening under vibration without requiring a separate washer. The bolt is manufactured from AISI C1022 Grade 2 steel and finished with a zinc plating for basic corrosion resistance. It is fully threaded from the bearing face to the tip, making it suitable for through-hole and shorter clamping applications across a wide range of trade and industrial uses.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in HVAC equipment assembly, electrical enclosure mounting, plumbing fixture attachment, and general sheet-metal fabrication. The serrated flange face bites into the mating surface during torquing, eliminating the need for a lock washer in many standard installations. Its inch-series UNC thread makes it compatible with standard tapped holes and hex nuts used throughout residential and light commercial construction and equipment service work. Technicians working on unit replacements, bracket installations, or panel assemblies will find this a practical fastener for moderate-load, vibration-prone joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank — works with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003eSerrated flange diameter of 0.686 to 0.706 inches provides integrated vibration resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive head for standard socket or wrench installation\u003c\/li\u003e\n  \u003cli\u003eAISI C1022 Grade 2 steel construction for general-purpose mechanical strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion protection in indoor and light-duty environments\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head suits a wide range of clamping stack thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose inch-series fastener compatible with any 5\/16-18 UNC tapped hole or standard hex nut in residential and light commercial mechanical, electrical, and plumbing assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex socket or open-end wrench sized for a 5\/16-inch hex head. Ensure mating threads are clean and free of debris before installation. The serrated flange requires direct contact with the clamping surface to function as a locking element — do not install over a flat washer unless a separate locking method is also used. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for Grade 2 steel fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 inches\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: 0.686 to 0.706 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: 1.25 pounds\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: 3132MWW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697833083186,"sku":"3132MWW","price":1364.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ca656e8c736c44ed8b4bf51cefa56a_4133319c-4aaa-487e-9eb8-8ea25b9953b5.jpg?v=1788354773","url":"https:\/\/voomisupply.com\/products\/value-collection-3132mww-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
