The serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt carries a 3\/8-16 UNC thread and measures 0.5 inches in length under the head with full threading from tip to flange. It is driven with a standard hex drive. Tradespeople and maintenance professionals working on mechanical assemblies, equipment frames, and structural brackets reach for this fastener when vibration resistance is a priority.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general industrial, mechanical, and maintenance applications requiring an inch-series UNC fastener. Its fully threaded shank makes it appropriate for thin-material clamping where thread engagement along the full grip length is needed. The zinc plating provides moderate corrosion resistance for indoor and light-duty outdoor environments. Typical users include millwrights, maintenance technicians, and contractors assembling steel-frame structures, machinery guards, brackets, and enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange integrates a locking washer face to resist vibration-induced loosening without a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fasteners\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-16 UNC shank allows maximum thread engagement in thin-material applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for general indoor and light-duty service environments\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard hex sockets and wrenches\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J429 dimensional and strength standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC serrated flange bolt for use in any application requiring a 3\/8-16 thread and 0.5-inch grip length under the head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized for 3\/8-inch hex flange bolts. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating appropriate for Grade 5 fasteners at this thread size as specified by the applicable mechanical or structural code. The serrated flange face should seat directly against the workpiece surface — do not add a flat washer between the flange and mating surface, as this defeats the anti-loosening serrations.\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\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: 0.5 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\u003eFlange Diameter\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Serrated\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.6.3, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0415 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: 825112MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716207673650,"sku":"825112MSC","price":5803.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d66bd7d27ce3941d1ee14dd75900957.jpg?v=1788523202","url":"https:\/\/voomisupply.com\/products\/value-collection-825112msc-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
