It features a 1\/2-13 UNC thread with a 3-inch length under the head and is fully threaded from the flange to the tip. The integrated serrated flange distributes load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Made from AISI C1022 Grade 2 steel with a zinc-plated finish, this bolt suits general-purpose fastening applications where corrosion resistance and reliable clamp load are required. Installation is performed with a standard hex wrench or socket.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for residential and light commercial construction, mechanical equipment mounting, and general fabrication work. The serrated flange eliminates the need for a separate lock washer in most applications, reducing hardware count and assembly time. Typical uses include structural panel attachment, equipment frames, and similar assemblies where vibration-induced loosening is a concern. This fastener uses inch-based dimensions and UNC thread form, making it compatible with standard imperial tooling and hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC fully threaded shaft, 3 inches length under head\u003c\/li\u003e\n  \u003cli\u003eSerrated flange bearing surface resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 1.02 to 1.07 inches for broad load distribution\u003c\/li\u003e\n  \u003cli\u003eAISI C1022 Grade 2 steel construction for general-purpose strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive for use 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 imperial fastener compatible with any assembly using 1\/2-13 UNC threaded holes requiring a serrated flange bolt with a 3-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified mechanic, millwright, or trade professional using a standard hex socket or open-end wrench sized for a 1\/2-inch bolt head. De-energize and lock out any equipment before fastener service. The serrated flange requires a clean, flat mating surface to seat properly and achieve full anti-loosening effect. Do not use an additional lock washer between the flange and the mating surface, as this negates the serration contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 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: 1.02 to 1.07 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\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.01 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: 406338PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698155356466,"sku":"406338PS","price":1281.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ca656e8c736c44ed8b4bf51cefa56a_d95ff40c-c712-4f31-b383-6a654aaeaaf9.jpg?v=1788358596","url":"https:\/\/voomisupply.com\/products\/value-collection-406338ps-serrated-flange-bolt-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
