Threaded to the 1\/4-20 UNC standard with a full thread length of 2-3\/4 inches under the head, this bolt uses a hex drive for standard wrench or socket installation. The serrated flange distributes load across the bearing surface and bites into the mating material to resist loosening from vibration. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, it balances moderate tensile strength with basic corrosion protection for general-purpose use.\u003c\/p\u003e\u003cp\u003eThis serrated flange bolt is suited for light to medium-duty mechanical assemblies in HVAC equipment, electrical enclosures, equipment panels, ductwork brackets, and similar trade applications where vibration resistance is a priority. The fully threaded shank provides maximum thread engagement across a range of material thicknesses. The zinc-plated finish offers adequate protection in dry or mildly corrosive indoor environments. Installation requires only a standard hex wrench or socket and no separate lock washer is needed due to the integral serrated flange.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSerrated flange provides integral vibration-resistant locking — no separate lock washer required\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-3\/4 inch shank allows maximum thread engagement across varying material thicknesses\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread standard for broad compatibility with standard nuts, inserts, and tapped holes\u003c\/li\u003e\n\u003cli\u003eHex drive accepts standard wrenches and sockets for fast installation and removal\u003c\/li\u003e\n\u003cli\u003eAISI C1022 Grade 2 steel construction with zinc-plated finish for general indoor use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC serrated flange bolt for use with any tapped hole, nut, or threaded insert conforming to the UNC inch fastener standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard hex wrench or socket matching the bolt head size. De-energize and lock out any equipment before fastening or removing hardware on electrical or mechanical assemblies per applicable OSHA lockout\/tagout procedures. Do not exceed the torque rating appropriate for Grade 2 steel at this thread size — consult a standard fastener torque chart for the correct value. Inspect the mating surface and threads for damage before installation to ensure proper seating of the serrated flange.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 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\u003eFull or Partial Threading\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: 0.513 to 0.531 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 Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.86 pounds\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: 1444MWW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695249064242,"sku":"1444MWW","price":5015.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ca656e8c736c44ed8b4bf51cefa56a_7182878f-56b8-4588-b9ad-d4211e7ae17c.jpg?v=1788333137","url":"https:\/\/voomisupply.com\/products\/value-collection-1444mww-serrated-flange-bolt-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
